FARM HANDICRAFT FOR SCHOOLS. 13 
Note to Teacher. — This exercise may be correlated with drawing, language, or 
geography, as well as agriculture. Have the pupils make a drawing of the house to 
scale. Let them design and build other types of houses and put them up at home 
and about the school yard. See list of references given, especially Farmers' Bulletin 
609. Language-lesson topics that may be used are: Birds, the Farmers' Friends, 
Food of Birds, Nature Study and Birds, and Where Birds Migrate. As a geography 
lesson have the pupils locate the States to which the birds migrate and study the 
climatic conditions of these States. As lessons in agriculture make studies of the 
feeding habits of birds and learn what weed seeds and insects are eaten by birds. 
Learn methods of keeping crows from taking freshly planted corn.

EXERCISE IV. SEED GERMINATOR. 
In figure 22 is shown a type of seed germinator that is very con- 
venient for testing seed corn. The box is divided into squares by 
broom wire or cord. Sand or soil is placed hi the box, and the kernels 
are planted in the squares. The rows of squares are numbered one 
way of the box and lettered the other way. Each square can then 
be designated by a number and a letter in the same manner as cities 
and countries are often designated on maps. For example, the upper 
left hand square is A 1, the upper right hand one, A 10. When corn 
is to be tested, the ear from which a group of kernels is taken is desig- 
nated by the same letter and number as the square in which it is 
planted.
