centimeter sieve are planted 21 to the row, and the 5-centimeter 
bulbs are planted 35 to the row. All bulbs which pass a 5-centimeter 
sieve are strewn along, about 50 to the row. The foiirteens, twenty- 
ones, and thirty-fives are planted in 7 clusters of 2, 3, and 5, respec- 
tively. 
THE PLANTING RECORD. 
The record made at planting time furnishes the basis for all com- 
putations on the grower's inventory. In bulb culture the grower is 
constantly dealing in large numbers. At present we are putting 
little short of 350,000 bulbs on an acre. It is desirable to have a 
reasonably accurate estimate of these without the labor of actually 
counting them. This is accomplished by getting a count of the 
number of rows of each size planted. To accomplish this, one of the 
boys who sets bulbs keeps the tally and when a change of size is 
made calls the number of rows of each size planted to the foreman of 
the planting crew, who jots down the number in the proper space 
in a notebook previously ruled. The form of this record is shown in 
Table 1.

Adding the horizontal column gives the total number of rows 
planted to any one variety. This can also be obtained by multi- 
plying the number of running feet of a 3-foot bed by 2, since the rows 
are 6 inches apart. To arrive at the number of bulbs of any size 
planted, the figure representing the number of rows must be multi-
