WINDOW BOXES 
Boxes that can be placed on the inside window sill 
during the winter and moved to the projecting ledge 
outside in the summer are convenient for teaching 
pupils how to use and appreciate the value of window 
boxes, as well as porch boxes, which are becoming very 
popular in many cities, where they frequently provide 
the only opportunity for cultivating house plants in 
the open air. 
The box should be made from wood and should be 
seven inches deep and eight or ten inches wide. The 
length may be made to fit the width of the window. 
Six or eight inch holes should be bored in the bottom 
of the box for drainage. 
A zine tray one inch deep and an inch wider and 
longer than the box must be made, to receive the drain- 
age. This should be used outside as well as in the room, 
for drainage from plants will leave streaks on the wall if 
permitted to run down on the outside. The box should 
be raised a fourth of an inch from the bottom of the 
tray to allow space for water below. 
A compost consisting of one third garden soil or 
fibrous loam, one third well-rotted barnyard manure, 
and one third sand, sifted through a quarter-inch screen,
