GARDENS AND THEIR MEANING 
The first cold frame, for instance, used in the Boston 
school gardens was made of planks nailed together to support 
a window sash three feet by six. This old double window 
belonged to the schoolhouse and had been lying discarded 
for years in the basement. Suitable soil was made by mixing 
loam with barnyard manure. Several hundred plants were 
easily grown here at one time, and there was space for many 
NORMAL-SCHOOL STUDENTS WORKING AT THE COLD FRAME 
more seeds. In the frame were started different kinds of 
early vegetables ; and these got under way a good month be- 
fore the weather permitted planting outdoors. Lettuce, cab- 
bage, tomatoes, spinach, and parsley throve here beautifully. 
By the time these had made a good start and had been pricked 
out once, — in other words transplanted to other boxes, — it 
was mild enough to transplant them to open ground. Need- 
less to say, it was worth the trouble.
