io8 NATURE STUDY BY GRADES 



Small samples of different kinds of wood may be prepared 

 of uniform size and shape, planed; the lower half may be 

 finished in oil, or varnished to show the different kinds of 

 wood, and the effect produced by oil, stains, varnish, etc. 

 These samples, placed on a card or thin board, will form a 

 very useful piece of apparatus. 



Test the hardness, strength, and weight of different kinds 

 of wood, and suggest suitable kinds for various uses. What 

 kind is used for floors? doors? shingles? chairs? wagon 

 tongues? whipstocks? carriage spokes? Tell why each is 

 suitable for the use assigned. Mention woods that are 

 tough ; others that are hard ; others that are soft, etc. Test 

 in various ways these properties in samples of wood that may 

 be obtained.
