The Time for Planting 
The average dates 
of first frosts in au- 
tumn are shown on the 
map on page 159. In 
making this map effort 
was made to leave the 
zones the same as in 
Fig. 88, but the boun- 
dary lines do not coin- 
cide, because different 
localities having the 
latest killing spring 
frosts at the same 
time do not always 
have the first killing 
frosts of autumn at 
the same time. The 
map, however, aids one 
in judging the proba- 
ble date when the first 
autumn frost will kill 
garden crops.

Then burlap bags, old mattings or carpets, 
or any other coverings are spread over the 
boards. Sometimes the season for vegeta- 
bles like beans, tomatoes, peppers, and egg-

tecting the plants on the one night of the

whether the entire growing season is too short for a 
crop to reach maturity.
