"A novel find was made Monday by Joe King Lema at the shore near Railroad pier. It was a real white whale, the second of the species, it is believed, ever captured so far south of the cruising grounds.
David C. Stull purchased the whale immediately after the capture and will send it to Boston."

"Still another batch of unnamable stuff of greasy substance, supposed by the sender to be ambergris, was received last week by Mr. David C. Stull. The sample came from the Grand Caymans, the sender being the man who purchsed  fishing schooner Dido at this port a few years ago."

Provincetown Advocate, 1 Feb 1917
"Again the graceful and fortunate whaling brigantine Viola is the subject of excited comment in all whaling and fishing circles. A record breaker, as money maker while on her maiden voyage, a 'lucky ship' on each intervening cruise, she now breaks the silence that had lasted since her sailing from New Bedford September 25, 1916, with the most cheering message sent out from her side during all her career. Writing somewhere off Cape Frio, December 19th, last, the commander of the Viola, Capt. Joseph F. Lewis, stated that the brig had taken 450 barrels sperm oil and 150 pounds of ambergris. The letter was brought to land by a Norwegian steamer which fell in with the Viola at sea.
On her first voyage the Viola not only took a remarkably large lot of oil, but, as partner with whaling bark Bertha, a lump of first quality ambergris. That lot of the much prized substance weighed 165 pounds when first lande in the States, losing a few pounds by drying before the sale was made, and profits were divided fifty-fifty between the brig and the bark's owners.
In this instance, we believe, th Viola is the sole possessor of a lot weighing 150 pounds, the price of which will be governed largely by the quality. If the stuff is of first chop grade, as is hoped by all, voyage profits exceeding even those of the record breaking first cruise will have been amassed in the amazingly short time of three months. In any event, bully for the Viola!

Provincetown Advocate, 1 Feb 1917
"Mr. David C. Stull has been favored with an order for watch oil by the agent of a Japanese concern, or the Japanese government. In 1916 this company, or government, representative placed  with Mr. Stull an order for one thousand bottles of his oil. That the first lot met with the approval of the buyer is evident, the second order being for twice the quantity of the first, of two thousand bottles. Bottles, with patent stoppers of glass for the same, have arrived at the Stull factory and work of filling same will be done soon."

"A 27-foot-long whale was caught in Yarmouth fish weir a few days ago. For two or three days the creature remained alive, defying the attempts of the fishermen to cause its death with bullets fird from a rifle. Then Captain Charles A. Foster showed the men how to do the trick and one stab of the lance put the mammal out of its misery. Our townsman, David C. Stull, bought the whale. Messrs. Burch and Veara, experienced whalemen, went Monday to the scene and flensed the whale. The blubber was shipped further a field, for rendering, and the pair next removed the meat from the bones, which they disarticulated, for shipping to this town. The bones arrived here yesterday. They are to be assembled and the whale skeleton, mounted, will probably soon grace some city museum as Mr. Stull is in communication with scientific bodies, lookin to its sale."

---
It is true that Mr. David C. Stull secured the promise of the 90-odd blackfish that stranded at Eastham last Saturday, but, as the town authorities ordered that all carcasses should be buried, the deal was declared off and the great hoard of oil-yielding blubber, worth probably $3000 or more (if rendered into oil) went, perforce of circumstances, to waste."


Provincetown Advocate, 5 Sep 1918
"Mr. David C. Stull went the past week to East Dennis and purchased the small herd of blackfish that had just stranded there, saving not only the blubber but all the meat."

"An old time occupation was revived last Sunday when a school of about 75 blackfish came in near the Bay Shore and the men of the village went off with boats and succeeded in landing about sixty on the beach. They were sold to David Stull of Provincetown who, with his men, began work on them Tuesday."


Provincetown Advocate, 22 Aug 1918
"To the end that a new source of food may be made available for public consumption, Hugh M. Smith, Commissioner, has written to Henry B. Endicott, Federal Food Administrator, suggesting that the latter take up with the State Authorities or with the Boards of Health the matter of remission of the penalties imposed under the law approved May 28, 1918, prohibiting the driving of blackfish ashore on the ground that they constitute a menace to public health and a nuisance. In this communication Mr. Smith states that it is the opinion of the Bureau (Fisheries) that properly conducted this industry cannot menace the health of the communities where it is carried on, and states that it is within his knowledge that on, or about, August 4th, 130 of these large cetaceans were driven ashore at Nantucket, and that this school alone, if it had been properly utilized, would have yielded not less than 250,000 pounds of meat.
Of our townsman, Mr David Stull, Commissioner Smith then wrote: "He has been long and favorably known to this Bureau in connection with the whale oil industry. He has been largely instumental in utilizing for industrial purposes the considerable numbers of balckfish which from time to time have gone ashore on the coast of Massachusetts, and induced by this Bureau's campaign for the introduction of whale meat as food, is now considering the use of blackfish meat for the same purpose.
The Bureau will appreciate anything that you may be able to do which will permit Mr. Stull to carry on the operations proposed under such safeguards as will ensure public health and the production of food.'
'The blackfish, or Pilot Whale, is a gregarious, hot-blooded, red-blooded animal. Its meat is as red and firm as that of land-living beef cattle.
Like the cow on land, the female blackfish suckles her young, and, as the meat is nutritious and palatable and the average adult yields many hundreds of pounds of 'sea beef,' it should not be difficult to devise means for the quick stripping and storing of vast quantities of a valuable food that has heretofore been permitted to go to waste.' "

"'Was that grand old whaling schooner, the John R. Manta a relative of yours?' genial, veteran Selectman John R. Manta was asked.
'Yes,' said John, 'It was named after me by my father, Joseph Manta, and it was one of the finest boats he ever owned.'
What is left of the Manta now are memories, the man after whom the stately vessel was named, and a book which has just been published by Reynolds Printing of New Bredford, 'There Goes Flukes' written by William H. Tripp, Curator of the New Bedford Whaling Museum, recounting his adventures on the last whaling trip ever made by the Manta, commanded by Captain Antonio J. Mandly. And this trip, too, was the last ever made out of New Bedford, which, at one time, becasue of its trade in oil, was on its way to rivaling the port on New York in shipping importance.
Provincetown plays an important part in 'There Goes Flukes.' Naturally many of the names mentioned are those of Provincetown men and one of the most interesting and informative chapters concerns ambergris and David Stull, the'Ambergris King.'
Why the 'King'
'They call me the 'Ambergris King', and I'll tell you why they call me that' Stull is quoted in answer to a question concerning some of the famous ambergris catches. 'You see,' he goes on, 'I know all about it. Like anything else, a man's got to be trained to ambergris.'
'See what I have here,' he said as he called the author's attention to a ring on one of the fingers of his left hand. Set in the ring was a large rectangular stone, known as goldstone. Much to Mr. Tripp's surprise, Stull raised the goldstone, with a fingernail, as one would the cover of a box, and inside the depression of the ring was a depression filled with a black, sticky substance.
'That's ambergris' he said, 'but of a very poor quality. Some of a small lot I bought once. It was no good because it would never dry as it should. I keep that in my ring to show people what poor ambergris looks like.' [incomplete transcription]

Natural History Magazine, March-April 1933, "Floating Gold; The Romance of Ambergris," by Robert Cushman Murphy
The career of a museum naturalist is sometimes regarded as a dusty one, but among its amenities are the unforeseen calls of interested, curious, inquisitive, mysterious, or merely crack-brained individuals, who, by one pretext or another, find their way into his laboratory with something to be identified. A preliminary sifting out by the man at the information desk usually staves off the bearer of a rock crystal from disturbing the curator of insects, or the proud owner of a hippopotamus tooth from barging into the department of Peruvian archaeology. However, there is no dependable bulwark against surprises.
...
Now of all the things presented for the inspection of that faithful servant of the public, the museum curator, the most romantic, and the least likely to be true, is ambergris. I say inspection, because identification is preconceived in the mind of the finder. His treasure, stumbled upon along the sea beach, recognized with the sudden surmise that dawns like knowledge from a previous incarnation, is encountered where ambergris belongs; it looks, and feels, and smells as ambergris should and, since it bears no resemblance to anything familiar, it follows that riches are already within his grasp.

However, confirmation is the capstone to personal certainty. "Some funny old cove at the Museum," the finder reasons, "will know all about it. Moreover, such a practical thought as trying to horn in on my profits would never enter his head. Those museum birds don't care about money, anyway. It will be a good idea to have it settled scientifically before I see the man who buys the stuff for Coty."
...
 in the year 1672 an Englishman revealed the pertinent contents of a manuscript which had been found on board a captured Dutch East Indiaman. This document stated that

'Ambergris is not the scum or excrement of a whale, but issues out of the root of a tree, which tree, howsoever it stands on the land, alwaies shoots forth its roots towards the sea, seeking the warmth of it thereby to deliver the fattest gum that comes out of it, which tree otherwise by its copious fatness might be burnt and destroyed; wherever that fat gum is shot into the sea, it is so tough that it is not easily broken from the root, unless its own weight and the working of the warm sea doth it, and so it floats on the sea.... If you plant the trees where the stream sets to the shore, then the stream will cast it up to great advantage.'

Layoff hunting for ambergris, boys; all you need to find is the ambergris tree!
...
It remained for the empirical Quaker whalemen of Nantucket to settle the question beyond doubt, as related by Doctor Boylston, a surgeon of Boston, about the end of the first quarter of the Eighteenth Century. Reports the doctor:

"The most learned part of mankind are still at a loss about many things even in medical use, and particularly were so in what is called ambergris, until our fishermen of Nantucket, in New England, some three or four years past made the discovery. Their account to me is as follows:—cutting up a spermaceti bull-whale, they found accidently in him about twenty pounds weight, more or less, of that drug; after which, they and other such fishermen became very curious in searching all such whales they killed, and it has been since found in lesser quantities in several male whales of that kind, and in no other, and that scarcely in one of a hundred of them."

And so the matter rests, except that female sperm whales have since proved to share the honor with their larger mates. Encyclopedic works of much later date than the note of Doctor Boylston still continued to publish nonsense about a "fossil bitumen or nephtha, exuding out of the bowels of the earth in a fluid form and distilling into the sea, where it hardens and floats," but few have been misled. In the light of modern knowledge, which appears to be none too exact on the subject, ambergris is regarded as a morbid secretion of the liver or intestines of the sperm whale. Whalemen have long agreed that it is the sick whales that yield the prize, and the legion of books on maritime adventure, credible and incredible, unite in stating that emaciated whales, capable of supplying a minimum of oil, were nevertheless greeted with a warm welcome and a ready lance by the Yankee blubber-hunters, on the slim chance that the victim might more than make up from his in'ards what he lacked in his skin.

Out at Provincetown, on the hooked tip of Cape Cod, my late friend Captain D. C. Stull spent most of a long lifetime engaged in the stimulating vocation of a purchaser and wholesaler of ambergris and of porpoise-jaw oil. From the latter is refined the delicate lubricant for watches and chronometers. Whenever a herd of blackfish stranded anywhere along the northeastern coast of the United States, Captain Stull, who walked with a limp but who covered the ground more rapidly than most of mankind, was apt to be the first practical man on the spot, prepared to buy the animals for cash from fishermen or townships, and undertaking to tow all the objectionable carcasses safely out to sea as soon as he had removed the rich blubber of "junk and jaw," these being the only parts that yield the fine oil. In like manner, if a New Bedford whaler reported to her owners a haul of ambergris, Captain Stull would at once open negotiations, and would be waiting at the dock when the ship came home. Equally ready was he to deal with possibly lucky beachcombers of the sort mentioned at the beginning of my story, and his experiences in receiving bits of all the worthless substances that are buoyant in salt water were, naturally, far more diverse than my own. Most such he treated with a chuckle, and the untrustful reactions of persons who impugned his motives in telling them the bitter truth about their discoveries, only added to his good-natured merriment. After all, the chap who appears with "genuine ambergris," whether pre-war or not, is to be received with only slightly more credulity than the inventor of a perpetual-motion machine. In either case the burden of proof is squarely up to the seller.

And so although watch-oil was his staple, Captain Stull obtained and disposed of a considerable quantity of ambergris during the course of several decades. The marketing was his own business secret. Because of the relatively minute amount of the extract required by all the perfume manufacturers of the world, the ambergris exchange has its own curious technique. Like the stock exchange, it is subject to more or less unpredictable fluctuations. A large catch may cause a glut, with a corresponding drop in the current price. Therefore it does not always pay to find, or to admit ownership of, too much; you may get more for less. While Captain Stull was ever ready to buy, he did not always choose to sell, and how much of the strange material he may have had stowed away in his strong-box, nobody but he was in a position to know.

Captain Stull perhaps shared a belief in the general weak-minded honesty and total lack of worldliness accredited to professional naturalists, for he was remarkably generous in turning over to me liberal samples of his choicest commodity. In fact, I have driven away in my Ford from Provincetown with my pockets stuffed with small bottles containing a king's ransom, all to be picked over at my convenience. Fresh ambergris, old ambergris, the best grade of gray, the poorest of black, ambergris that was mottled like marble, ambergris that looked like old cheese and smelt worse, ambergris that had the traditional fragrance of ploughed earth--it was all mine to handle and section, to examine under a microscope, and to return at my own will. My efforts resulted more in the verification of well known facts than in making startling new discoveries, but there was one conspicuous exception. In a sample from a sperm whale that had been killed off the south coast of Haiti during the year 1912, I found several bristles which were recognizable as the cheek-whiskers of a seal! Subsequent comparison with museum specimens showed that these belonged to the excessively rare, if not quite extinct, West Indian seal, an animal first met with by Columbus and long ago wiped out through most of its former range by insatiable hunters of oil and hides. Indeed, these whiskers from a whale's intestines constitute, so far as I have been able to ascertain, the latest zoölogical record of this little known seal. How long had they been encased in the waxy, preserving matrix of their strange tomb? The answer is bound up with two other still unsolved problems, namely how long does a whale live and how long may ambergris continue in its alimentary tract?
Other relics of whale banquets impacted in Captain Stull's samples were confined to the horny and indigestible beaks of squids or cuttle-fish, and to fragments of the internal shell or pen (what the canary bird eats) of the same creatures. Squids are ordinarily regarded as the exclusive food of the sperm whale, and their remains were the objects that originally gave a clue to the true source of ambergris. However, the ferocious potentialities of an aroused sperm whale have often been displayed to whalemen, and we now know that at least one After the bits of squid beak had been picked out of the lots of ambergris that passed through my hands, the residue was an ash-colored or darker substance which softened in the heat of the palm, and melted, below the boiling point of water, into a yellowish fluid resin. of the ocean-ranging monsters has strayed from the prescribed diet. An animal which could engulf a West Indian seal would have had no difficulty in taking in Jonah.

After the bits of squid beak had been picked out of the lots of ambergris that passed through my hands, the residue was an ash-colored or darker substance which softened in the heat of the palm, and melted, below the boiling point of water, into a yellowish fluid resin. At higher temperatures it volatilized into white vapor. "The dry lumps became electrified when they were rubbed slightly, so that they acted as magnets to re-attract all the squid beak that had been separated from them."

The French term ambre-gris (gray amber) was first applied to distinguish the material from ambre-jaune, yellow or true amber. The respective animal and vegetable origins of the two were discovered only within modern times, whereas both were immemorially known as stuffs cast up by the sea. Ambergris is an opaque, waxy, laminated solid, having an odor suggestive of musk or benzoin. (Benzoic acid, one of its components, also gives the tart taste to cranberries). The aroma is as subtly pleasing to the majority of human beings as catnip is to all feline creatures, from tabbies to tigers. Yet, strange to say, it is decidedly offensive to a few persons, and this without regard to the strength or purity of the solution.

"According to an obscure book entitled "The Last American Whale-Oil Company, a history of Nye lubricants, Inc., 1844-1994", by Ed Parr, 1996, David C. Stull was in business in 1896, when his porpoise-jaw oil was judged along with similar oils manufactured by Ezra Kelley and by The Nye Lubricants Company. The results of this study were presented before the Philadelphia Horological Society. According to the book, David Stull "refined a brand of oil for watches and clocks from the melons and jaws of toothed whales". He sold some of his oil to the Nye Lubricants Co.
The New Bedford Whaling museum has a circa 1900 postcard with the caption "D. C. Stull, Provincetown, Mass., cutting up blackfish to manufacture his watch and clock oil". It shows a photo of Stull on the beach with a stranded creature. This postcard is illustrated in the above mentioned book."

A Handy Book of Curious Information, by William Shepard Walsh, Philadelphia & London: JB Lippincott Co., pp 30-32
Ambergris (a French word meaning gray amber), a gray wax-like substance, believed to be the product of some disease in the sperm whale, analogous to gall-stones. It is found as a morbid secretion in the creature's intestines, and sometimes, after expulsion, floating on the surface of tropical seas. Its essential characteristic is a pungent and penetrating odor, so peculiar that art has never been able to contrive an imitation of it, though invention has been stimulated by the high price attendant on its scarcity. Inferior qualities bring eight dollars an ounce; the best, which is rarely seen, is rated at something like fifty dollars an ounce.

The largest single piece of ambergris known to whaling annals is said to have been found by Captain James Earle, of New Bedford, Mass., in the interior of a whale. It weighed 780 pounds, and was sold in chunks in various markets of the world for about $100,000.
...

The New York Sun recently published an interview with David C. Stull, who was known as the Ambergris King from the fact that he presided over the headquarters of the trade in Provincetown, Mass.

Good ambergris, he said, was worth more than twice its weight in gold. lie himself had once paid $18,000 for one lump and $30,000 for one lot. The lump weighed 98 pounds. At this rate a single ton would be worth a million dollars. He told a story of a Provincetown man who some thirty years before had been out on his first trip as captain of a whaling vessel. On his way home he stopped at one of the West India islands. A na.tive offered liim five small lumps of a dirtylooking substance, asserting that it was good for something, and explaining that he had got these pieces from a dead whale which was ashore on a certain beach. He added that there was plenty more in the carcass.

Did the captain-hoist all sail and get to that dead whale as fast as the winds of providence would permit? Not a bit of it. lie had been sent out after sperm oil and he'd stick to his job. So he gave the native a pair of blue overalls and a jumper for the five dirty lumps and went on his way.

After making port he showed the five lumps to Mr. Stull. When the latter gave him $700 for them he almost had a fit. Still that shock was nothing to what he got a little later, for he learned that another captain had heard of the dead whale, had got what ambergris still remained in the carcass, and had sold it in New York for $30,000. It was estimated that this whale must have contained at least $50,000 worth of ambergris. "But the whalers of to-day," concluded Mr. Stull, "are a more canny lot. In fact they have gone to the other extreme. They not only open up a captured whale the very first thing to look for ambergris, but they pick up from the flotsam of the sea all sorts of possible and impossible stuff under the fond delusion that they are taking a fortune aboard."
