can be made which if kept by the pupil will often be of value

Exercise No. 55. — Materials for Poultry Houses. — One or 

 more exercises devoted to figuring materials required to fill 

 a certain specification will be very helpful. A house of a 

 certain size and design can be described by one of the pupils 

 and then the entire class with the aid of the teacher can figure 

 out piece by piece the kind, size, and amount of material 

 required to build it. A house which is owned by one of the 

 students, or which one might wish to build will create more 

 interest. Figure materials in the following order : Sills, posts, 

 plate, studding, rafters, walls, roofs and miscellaneous mate- 

 rial. For values it is well to secure figures for lumber from 

 some lumber yard or local sawmill . At this time the meaning of 

 board feet and ways of measuring lumber should be explained.
