'stems, respectively: wheat, 94; barley, 110; oats, 87. As to 

 the effect of the increased size of the grains on the aggre- 

 gate of the crop, he adds that he has found one bushel of 

 his pedigree wheat, (original red,) produced from single 

 grains planted 12 inches by 12, to contain about 460,000 

 grains; a buslul of ordinary wheat containing 700^000 

 grains. The enlargement of the grains tend to a propor- 

 tional increase in measured yield. On three acres of land 

 he has averaged 72 bushels of wheat per acre from a seed- 

 ing of one-third of a bushel per acre, and on an entire field 

 of barley he has averaged, per acre, 82 bushels, weighing 

 57 pounds per bushel, from a seeding of one peck per 

 acre." 



In respect to regularity of drill, Major Hallett says: 



"My principle object is to insure perfect singleness and 

 regularity of plant with unformity of depth. The two latter 

 may be attained by the drill, as may the former also by 

 adopting the following plan : The seed-cups ordinarily used 

 in drilling wheat are so large that they deliver bunches 

 of grain, consisting of six or seven, which fall together 

 within a very small area, from which a less produce will be 

 obtained than if it had been occupied by a single grain. 



The additional grains are thus not only wasted, but are 

 positively injurious. By using seed-cups, however, which 

 are only sufficiently large to contain one grain at a time, a 

 stream of single grains is delivered, and the desired object, 

 viz., the depositing of grains singly, at once attained. The 

 intervals in the rows will not be exactly uniform, but they 

 will be sufficiently so for all practical purposes. The width 

 of these intervals will, of course, depend upon the velocity 

 with which the seed-barrel revolves, which can be regulated 

 at pleasure by proper arrangement of the cog-wheels which 

 drive it. By drilling thus we obtain the advantage of 

 the "broadcast" system, also equal distribution, as we can 

 have the rows close together and the grains as thin in the 

 rows as we please."
