and covered with boards or straw. All should be stored in a 

 well drained, shaded place, where frost remains late in spring. 

 I have had much more satisfactory results by freezing seed and 

 planting in the spring than by fall planting. Fall planted seed 

 are apt to germinate early, only to be killed by subsequent hard 

 frosts. Rich, warm soil should be chosen for forest tree seeds. 

 Sown in drills as early as possible in spring, in well prepared 

 land, enough trees can be grown on an eighth of an acre to plant 

 several ten acre groves. The farmer will find this treatment 

 more satisfactory than planting the seed where the trees are to 

 stand and more economical than any other. 



The oaks and walnuts are more difficult to transplant than 

 other species, and these will oftentimes succeed better when the 

 seed is planted in the grove. This can be most easily done by 

 leaving the places for such trees blank while planting, and in 

 the fall putting in two or three nuts or acorns in each place. 

 They should be covered to a depth of two or three inches, to 

 allow for wind action. 



STREET AND LAWN PLANTING. 



The ideal street tree is one that has a straight, clean trunk 

 with a well formed head and dense foliage. It must be able to 

 stand neglect, and must thrive under adverse conditions. It 

 should be as tree from insect pests as possible. It may either 

 have a compact, rounded head, like the hard _maple, or may 

 have extended branches, like the graceful elm. Its principal 

 purpose is to shade the walks and drives, hence dense foliage is 

 important. The list of valuable native' trees, suitable for street 

 planting is very limited, 



METHODS OF PLANTING. In planting street trees, it is im- 

 portant to dig large holes of greater depth than would seem 

 necessary for the tree. The surface soil should be kept separate 

 from the subsoil. Good, moist, black soil is put in the bottom 

 of the hole and about the roots, the subsoil being used used in 

 filling up. The soil should be tramped firmly about the roots 

 and it is often best to pour on a few pailsful of water in order to 

 bring it in close contact with the roots. As soon as planted each
