 work in the garden. Such plans could be made in early 

 spring or in the winter, and would help greatly when you 



come to work the 

 ground. Keep a record 

 of the approximate dates 

 of planting the differ- 

 ent vegetables, and the 

 number of rows or hills 

 to be planted. Later, 

 when vacation comes,

 manufactured by taking an old storm window or any 

 small window as a top, and fitting it over a frame made
