The rain was beneficial to about a thousand grains of Cape of Good Hope wheat that Washington had just sown and by the thirty-first he was able to note that it was coming up. For several years thereafter he experimented with this wheat. He found that it grew up very rank and tried cutting some of it back. But the variety was not well adapted to Virginia and ultimately he gave it up.

In this period he also tried Siberian wheat, put marl on sixteen square rods of meadow[4], plowed under rye, and experimented with oats, carrots, Eastern Shore peas, supposed to be strengthening to land, also rib grass, burnet and various other things. He planted potatoes both with and without manure and noted carefully the difference in yields. At this time he favored planting corn in rows about ten feet apart, with rows of potatoes, carrots, or peas between. He noted down that his experience showed that corn ought to be planted not later than May 15th, preferably by the tenth or perhaps even as early as the first, in which his practice would not differ much from that of to-day. But he came to an erroneous conclusion when he decided that wheat ought to be sown in August or at the latter end of July, for this was playing into the hands of his enemy, the Hessian fly, which is particularly destructive to early sown wheat. Later he seems to have changed his mind on that point, for near the end of his life he instructed his manager to get the wheat in by September 10th. Another custom which he was advocating was that of fall and winter plowing and he had as much of it done as time and weather would permit. All of his experiments in this period were painstakingly set down and he even took the trouble in 1786 to index his agricultural notes and observations for that year.

[4] "On sixteen square rod of ground in my lower pasture, I put 140 Bushels of what we call Marle viz on 4 of these, No. Wt. corner were placed 50 bushels--on 4 others So. Wt. corner 30 bushels--on 4 others So. Et. corner 40 bushels--and on the remaining 4-20 bushels. This Marle was spread on the rods in these proportions--to try first whether what we have denominated to be Marie possesses any virtue as manure--and secondly--if it does, the quantity proper for an acre." His ultimate conclusion was that marl was of little benefit to land such as he owned at Mount Vernon.

Many of his experiments were made in what he called his "Botanical Garden," a plot of ground lying between the flower garden and the spinner's house. But he had experimental plots on most or all of his plantations, and each day as he made the rounds of his estate on horseback he would examine how his plants were growing or would start new experiments.

The record of failures is, of course, much greater than of successes, but that is the experience of every scientific farmer or horticulturist who ventures out of the beaten path. Even Burbank, the wizard, has his failures--and many of them.

One of Washington's successes was what he called a "barrel plough." At that time all seed, such as corn, wheat and oats had to be sown or dropped by hand and then covered with a harrow or a hoe or something of the kind. Washington tried to make a machine that would do the work more expeditiously and succeeded, though it should be said that his plans were not altogether original with him, as there was a plan for such a machine in Duhamel and another was published by Arthur Young about this time in the Annals of Agriculture, which Washington was now perusing with much attention. Richard Peters also sent yet another plan.

Washington's drill, as we should call it to-day, consisted of a barrel or hollow cylinder of wood mounted upon a wheeled plow and so arranged that as the plow moved forward the barrel turned. In the barrel, holes were cut or burnt through which the corn or other seed could drop into tubes that ran down to the ground. By decreasing or increasing the number of holes the grain could be planted thicker or thinner as desired. To prevent the holes from choking up he found it expedient to make them larger on the outside than on the inside, and he also found that the machine worked better if the barrel was not kept too full of seed. Behind the drills ran a light harrow or drag which covered the seed, though in rough ground it was necessary to have a man follow after with a hoe to assist the process. A string was fastened to this harrow by which it could be lifted around when turning at the ends of the rows, the drill itself being managed by a pair of handles.

Washington wrote to a friend that the drill would not "work to good effect in land that is very full either of stumps, stones, or large clods; but, where the ground is tolerably free from these and in good tilth, and particularly in light land, I am certain you will find it equal to your most sanguine expectation, for Indian corn, wheat, barley, pease, or any other tolerably round grain, that you may wish to sow or plant in this manner. I have sown oats very well with it, which is among the most inconvenient and unfit grains for this machine.... A small bag, containing about a peck of the seed you are sowing, is hung to the nails on the right handle, and with a small tin cup the barrel is replenished with convenience, whenever it is necessary, without loss of time, or waiting to come up with the seed-bag at the end of the row."

As Washington says, the drill would probably work well under ideal conditions, but there were features of it that would incline, I have no doubt, to make its operator swear at times. There was a leather band that ran about the barrel with holes corresponding to those in the barrel, the purpose of the band being to prevent the seeds issuing out of more than one hole at the same time. This band had to be "slackened or braced" according to the influence of the atmosphere upon the leather, and sometimes the holes in the band tended to gape and admit seed between the band and the barrel, in which case Washington found it expedient to rivet "a piece of sheet tin, copper, or brass, the width of the band, and about four inches long, with a hole through it, the size of the one in the leather."
