Turning to the whaling industry, Jefferson noted that Americans did not enter it until 1715, although he credited the Biscayans and Basques of Southern Europe with prosecuting it in the 15th century and leading the way to the fishing grounds off Newfoundland. Whales were sought in both the North and South Atlantic. The figures for the American Colonies in 1771 as given by Jefferson were 304 vessels engaged, totaling 27,800 tons, navigated by 4,059 men.
They were in for a difficult time in 1791. The Revolution halted their activities and deprived them of their markets. Re-establishing this fishery was a prime concern of Jefferson.
It is significant that in his painstaking consideration of the nation's fisheries he, a Virginian, apparently found no cause to deal with those of his own Chesapeake bay. They were one day nevertheless to outstrip many times over both the volume and value of American cod and whale fisheries together.
The evidence is that Jefferson was more interested in fish at Monticello than anywhere else. But there the interest was personal, not national. In his so-called Farm Book, or plantation record, he often mentions fish. A note on slave labor reads: "A barrel of fish costing $7. goes as far with the laborers as 200 ponds of pork costing $14." This was in all probability Virginia salt-herring, which had finally reached the status of a staple during the latter half of the 18th century. An 1806 memorandum to his overseer runs: "Fish is always to be got in Richmond ... and to be dealt out to the hirelings, laborers, workmen, and house servants of all sorts as has been usual." In 1812 a bill for fish, which he terms "indeed very high and discouraging, but the necessity of it is still stronger," lists the species no doubt in chief demand: "Twelve barrels herrings, $75. and one barrel of shads, $6.50." These were salted and shipped in from Tidewater fisheries like George Washington's at Mt. Vernon.
For fresh fish Jefferson and his neighbors could look to their adjacent rivers. In fact, so greatly did they rely on them that it was with feelings akin to consternation that he wrote his friend William D. Meriwether in 1809 that a neighbor, Mr. Ashlin, proposed to erect a dam which was sure to inconvenience the watermen of the vicinity. Furthermore, "to this then add the removal of our resort for fresh fish ... and the deprivation of all the intermediate inhabitants who now catch them at their door." He was not on too firm ground in objecting, however. He had a dam of his own across the Rivanna river which had been there since 1757.
He decided to build a fish pond in his garden. As he described it in 1808 it was little larger than an aquarium, 40 cubic yards contents, probably for water lilies and goldfish. It was the first of several fish ponds, constructed, no doubt, with both beauty and utility in mind. A note in his Weather Memorandum Book under date April 1812 tells us: "The two fish ponds on the Colle branch were 40 days work to grub, clean and make the dams."
A series of letters in 1812 to friends who he thought might supply him with live fish, particularly carp, for stocking, all run very much on the order of this one to Captain Mathew Wills:
I return you many thanks for the fish you have been so kind as to send me, and still more for your aid in procuring the carp, and you will further oblige me by presenting my thanks to Capt. Holman & Mr. Ashlin. I have found too late, on enquiry that the cask sent was an old and foul one, and I have no doubt that must have been the cause of the death of the fish. The carp, altho it cannot live the shortest time out of water, yet is understood to bear transportation in water the best of any fish whatever. The obtaining breeders for my pond being too interesting to be abandoned, I have had a proper smack made, such as is regularly used for transporting fish, to be towed after the boat, and have dispatched the bearer with it without delay, as the season is passing away. I have therefor again to solicit your patronage, as well as Captain Holman's in obtaining a supply of carp. I think a dozen would be enough and would therefore wish him to come away as soon as he can get that number.
From that time on his ponds came in for periodic mention, as when one was broken up by flood waters in 1814. But despite setbacks he kept faith in them as good food-producing adjuncts of a farm, thus anticipating the U.S. Department of Agriculture's modern food-fish pond-development program by more than a century.
As is likely to be the case with experimenters, Jefferson's efforts at fish propagation do not appear to have been overwhelmingly successful. At any rate, there is much more frequent reference in his records to putting fish in his ponds than taking them out. So far as he was concerned, it may be said that results were less important than example. Like all great leaders he was an originator and investigator, confining himself to the basic things that insure man's sustenance and contribute to his happiness, not the least of which is fishing.
