fertilizers will be needed for a typical truck farm of IOC 
acres to supply the nearest city market? Problems in 
companion and succession cropping and rotation are ex- 
ceedingly valuable. Work of this character may consti-

it should be done between class periods. 
704. Definite lines of work.— As the character of the 
work undertaken will vary exceedingly in various local- 
ities, the following notes must be regarded as merely

to determine their adaptability for garden crops. 
Chapter IV, Tillage and Tillage Tools. — (1) Plow

early in the spring. Note the difference in the moisture

houses. (3) If possible, make an actual test of the im- 
portant types of hand and horse implements. 
Chapter V, Stable Manures. — (0 Make applications 
of various classes of manure for a few important vege- 
tables. Demonstrations with fresh and rotten manure 
should prove especially valuable. (2) Make a compost

Chapter VI, Green Manures and Cover Crops. — 
Study the character and extent of top and root growth 
of different classes of green manures and cover crops 
growing in the vicinity.

(2) Each student should mix and apply the materials

Various methods of application may also be tested.
