Before planting the seed it was dropped into water and the 
light seeds were skimmed off. ‘The seed was then sown on each 
plat in furrows 2 of an inch deep following the plan which was 
used with Crop II as stated on page 468. The seed was sown 
November 23, 1897, and the first germinations occurred November 
29. On Soils 9 and 11 the germination was less rapid and not so 
uniform as on the other soils. The seedlings which appeared on 
the first day of germination were comparatively few and hence 
were discarded; those which appeared on the second and third days 
were allowed to grow. In the case of Soils 9 and 11 it was found 
necessary to keep those which appeared on the fourth day also in 
order to have enough seedlings from which to select plants for 
the experiment. All other seedlings were promptly cut out. The 
seedlings were thinned December 9. As soon as they had devel- 
oped sufficiently to show which were most vigorous they were 
transplanted to permanent places in the same plat in which they 
were growing and set 84 by 9 inches apart. This was done De- 
‘cember 24. All seedlings were measured and those which were 
selected for transplanting were nearly uniform in size, varying 
no more than 1-4-inch in the plat and in the average not more than 
1-8-inch between different plats. A few of the plants, about 
1 per cent, afterwards damped off or were discarded for some 
other disqualifying reason; all others reached marketable size

given on page 479. The chemical analyses may be found on page 487.
