important that they should never be allowed to become cold enough 
to be frosted, as this no doubt is one of the principal causes of going 
to seed. 
Several methods are in use for making the plants stocky. 
Transplanting has already been mentioned, but this is an expensive 
process. Clipping the tops off lightly once or twice while in the beds 
is practiced to quite an extent. A few growers have a knife so 
mounted on wheels that it can be run under the plants, so as to 
cut off the tap root, thus causing more side roots to develop. 
Setting of Plants in the Field.— When the ground has 
been thoroughly prepared and danger of frost is over, the plants 
may be set in the field. If an early crop is desired it is, of course, 
necessary that the plants be set early, so as to give them as much 
time as possible to get their full growth. If the plants are crowded 
in the seed bed, it is a good practice to thin them and use the plants 
removed for the first setting. This gives the remaining plants a bet¬ 
ter chance. 
A small furrow is made and the irrigating water is turned into 
it. This settles the soil and puts it in good condition for setting the 
plants. After the water has seeped out of the ditch it is the plan of 
most growers to run a small stream into the furrow again. The 
surface of the water this second time leaves a line along the edge of 
the furrow and the plants are set along this line, thus making them 
all at the same level. In this way none of the young plants are 
covered when irrigated, and yet all are close to the water. Where 
Self-blanching is grown, a row is set on each side of the furrow, 
making two rows about twelve inches apart. Where Giant Pascal 
is raised, plants are set only on one side of the furrow, and that on 
the south side if the furrows run east and west, so that the plants 
may escape the reflection of the sun’s rays from the water. The 
furrows are made about four feet apart. The plants are set from 
six to eight inches apart in the row. With single rows four feet 
apart, plants eight inches apart in the row, 16,710 plants would be 
required per acre; with plants six inches apart in the row, 21,780 
plants would be used per acre. When Self-blanching is grown in 
double rows, just double this number of plants would be used. It 
is well to have an abundance of plants so that later on any vacant 
places may be filled. 
The beds are watered very thoroughly before removing the 
plants for setting, and then the plants may be pulled out singly by 
the roots if it is desired to thin the beds somewhat. The plants are 
arranged in bunches which can be held conveniently in the left 
hand. They are put in a box over which is thrown a wet sack to 
protect from the sun while being carried to the field. In setting, 
some simply lay a plant on the first finger of the right hand and 
stick it into the mud on the side of the furrow; others, where the soil
