470 ReEportT,oF THE HORTICULTURIST OF THE 
CROP IIl.* WINTER AND SPRING OF 1897. 
As soon as Crop If was removed, the soil in each plat was 
turned several times and given another application of acid phos- 
phate and sulphate of potash at the same rate as before, making 
the total application amount to 1,200 pounds of acid phosphate 
and 800 pounds of sulphate of potash per acre, including what had 
been applied for the previous crop. Soil 4 was thus changed to 
4a, 5 was changed to 5a and 6 was changed to 6a. 
Again the effort was made to avoid any differences in the 
growth of the plants which might come from unequal check to 
the growth in transplanting by planting several seeds in each 
place where a plant was to stand permanently, and afterwards 
removing all but one plant. February 18 about 10 seeds were 
planted in a place, covered with one-half inch of soil and lightly 
watered. Only plump, healthy looking seeds were planted. They 
were taken from the same packet which furnished the seeds for 
Crop II. March 15 the plants were thinned leaving one plant 
in each place.* , 
3 The size of the first leaf on March 15 was used as a guide in selecting the 
seedlings which were to remain so as to have them as nearly uniform in size 
as possible. The average measurements and the variation in size are shown for 
each plat in Table B. A comparison of this table with Table A, page 468, 
shows that greater uniformity in the seedlings was secured in this way than by 
the method of planting seeds of uniform weight which was followed for Crop I.
