in a smaller space, and therefore to hasten fruitfulness — 
perhaps an imaginary advantage—but more particularly 
to allow of an additionai stimulus to be given the plant 
at fruiting time by the addition of fresh soil. 
On the whole, however, we prefer to grow tomatoes 
on benches, with about 7 or 8 inches of soil. Fig. 14 
shows tomatoes growing upon a floor which lies directly 
over the heater, a place which gives most excellent re- 
sults. In this bed we set the plants in rows 24 inches 
apart, and 18 inches apart in the row. This house is

very light. In darker houses the plants cannot be set so 
close. Fig. 50 (page 156) shows a bed 3 feet wide (and 
only 4 inches deep) in which but a single row of plants is 
grown. We have grown an excellent crop of tomatoes 
on a bean bench, from which three crops of beans had 
been taken during the winter. After each crop of beans, 
the soil was loosened up and manure or manure water 
added if needed. The soil was again manured before 
the tomatoes were set. The bed is 6 inches deep. Upon 
this bed the plants were set 2 feet apart each way, and

carry a late crop of tomatoes upon benches which grow 
peas and lettuce during the winter. Such houses are not
