Epitome. — From a general .study of the .subject, it appears that 

 in interior localities dense plantings are advisable, tight hedges 

 being often recommended. In localities influenced by bodies of 

 water, however, it is evidently better practice to plant a belt sim- 

 ply for the ptirpo.se of breaking or checking the force of the warmer 

 winds, still allowing tlien? to pass in their coiu'se. Such a belt 

 gives the desired shelter to trees when laden with fruit and ice, 

 and may hold the snow, while danger from comparatively still 

 air is averted. The damage from still air is usually observed in 

 the lee of natural forests, and it is in such places that injury is 

 reported by Michigan correspondents. The writer has found no 

 indisputable evidence to show that such injury ever accompanies 

 artificial windbreaks ; places where such injur}' was reported have 

 been visited, but the loss of trees and fruit was plainly due to 

 age of trees or other obviotis rea.sons. Still, it is probable that 

 a hedge-like windbreak may .sometimes be the catise of mischief. 



The coarser evergreens, planted close together, are there- 

 fore advisable for interior places, while deciduous trees, or ever- 

 greens somewhat scattered, are often better for the lake re- 

 gions. In the.se latter cases, however, the lay of the land is 

 important, for if atmospheric drainage is good there is less danger 

 of injury from tight belts. Lower levels, upon which cold air 

 settles, are therefore more in need of open belts than higher lands. 

 For interior places, a strip of nattiral forest is the ideal windbreak. 

 In artificial belts, the kind recommended by Messrs. Yeomans, 

 and illustrated in Fig. i, is undoubtedly one of the best. The il- 

 lustration shows two rows of maples backing up a row of Norway 

 spruce. "The maples then receive and break the force of the 

 wind and prevent the spruces from becoming ragged. We never 

 shear the spruces."
