SUGGESTIONS FOR THE TEACHER 267 



man. Have the zinc trays made to fit the window sills or 

 better to fit shelves just below each window. If the windows 

 are wide have two trays for each because short trays are so 

 much easier to handle than long ones. A good size is 30 

 inches long, 8 inches wide, i J inches high. 



The paper flower-pots cost from twenty to forty cents a 

 hundred. Good sizes for school work range from the 2 J inch 

 to 3 J inch, the 3 inch size being most generally useful. 



A few water-tight zinc window boxes about four inches 

 high and of a length and width to fit the window are also very 

 desirable. A full discussion concerning the making and use 

 of these may be found in The School Garden Book. 



Identification of Specimens 

 The school may have an important influence on community 

 life by encouraging pupils to send specimens of unknown 

 insect enemies or fungous diseases, or of undetermined va- 

 rieties of fruits, grains or other crops to the State experiment 

 stations or the National Department of Agriculture. These 

 authorities will be glad to identify such specimens and to send 

 any desired information concerning them. The addresses
