EGG PLANT. 
The egg plant requires a warm, loamy soil and a long, warm 
season to grow to the best advantage. In Northern Colorado, the 
season is too short to allow the crop to mature if the seed are planted 
in the field, so that every advantage must be taken to prolong the 
growing period. The seed may be planted about March 15th in 
the greenhouse or hotbed in strawberry boxes or pots and treated 
much like cucumbers started by this method. They may be planted 
in flats and transplanted to pots when two true leaves have devel¬ 
oped. By doing this, the plants are of good size when the time 
comes for setting them in the field. Before finally planting them 
in the field, they should be hardened off in the cold frame. 
The seed and young plants require careful attention as to 
moisture and temperature for best results. They must not receive 
too much water, especially while the seed are germinating, and the 
temperature must not be allowed to fall too low. 
When set in the field the plants are put in rows three feet apart 
and eighteen to twenty-four inches apart in the row. They are 
given about the same cultivation as potatoes or tomatoes during 
the growing period. 
KOHL-RABI. 
Kohl-rabi is a vegetable with which the average American is 
not very familiar. It will grow well under the same conditions nec¬ 
essary for the production of good radishes and deserves to be cul¬ 
tivated wherever possible. 
Kohl-rabi is closely related to the turnip and produces a thick¬ 
ened stem or bulb above the surface of the ground. It has excel¬ 
lent quality and is sometimes called the “Lazy Man’s Cauliflower,” 
being cooked and served in a similar manner. 
The plant is hardy and can be grown in sections where the 
cauliflower cannot. The seed should be planted as early in the spring 
as possible in rows eighteen inches apart. The plants should later 
be thinned to stand six to eight inches apart in the row. Successive 
plantings at intervals of two weeks will insure a supply for a longer 
period. The vegetable should be gathered as soon as ready, which 
is about the time the swollen stems are one and a half to two inches 
in diameter. It remains in prime condition only a short time, so 
for best results must be used when just right. 
LETTUCE. 
Lettuce is the most important salad plant under cultivation 
and can be grown under a variety of conditions. The two types of 
lettuce most commonly cultivated are head lettuce and curly-leaved
