SCHOOL GARDEN. 



patent judges, Mr. George B. Emerson, Boston ; Mr. C. 

 F. Sargent, director of Harvard Botanic Garden ; Dr. 

 James C. Brown, of London, England ; Mr. Robert 

 Douglas, of Illinois ; Mr. Budd, of Iowa (see Dr. B. G. 

 Northrop's Economic Tree Planting), recommend the 

 following, either from seed or from saplings. 



TREES RECOMMENDED. 



Larch trees for durability, strength and resistance to 

 water. This tree is good for railway sleepers, as it holds 

 iron longer than any other wood, and does not corrode 

 it like oak. It attains maturity before the oak. Ten 

 acres of larch will furnish as much ship timber as 

 seventy-five acres of oak, because it can be planted 

 more closely. But the wood loses its hardness in rich 

 Western loam, or in too rich ground anywhere. 



The white ash is hardy, a rapid grower, and will bear 

 the bleakest exposures. It must have good soil ; but 

 it gives excellent wood for furniture and farm utensils. 

 The seed is abundant, and ripens about the first of Oc- 

 tober. If sown in the fall they should be covered with 

 three feet of straw ; if in the spring the seed must be 

 mixed with damp sand. Green bushes will protect the 

 seed in the hottest of summer weather. 



MAPLES. 



The rock maple grows perfectly in clayey soil. Nor- 

 way maple or sycamore, stands against Northern blasts 

 and sea-breezes. 



Red maple thrives in dry and gravelly soils. 



Maples should be planted twenty-five feet apart. 

 Elms should be planted from forty to fifty feet apart. 

 White oak, chestnut, hickory, butternut, white-pine and 

 willows will flourish in New England.
