THE SECRETAKY'S PORTFOLIO. 253 



the planting of certain trees may pass away and yet the trees be young and 

 only partially developed. It is only natural and quite proper that the planter 

 himself should desire to experience the benefit of shade from trees of his own 

 planting. Keeping in mind the space required for their perfect development, 

 and yet aiming at useful results as speedily as possible, it has become evident 

 by long experience and observation that street trees should be planted twice as 

 close as it is proper for them ultimately to stand, and when necessary every 

 other tree should be cut away. Planting the trees thus closely 18 or 20 feet 

 ■would be proper distances, so that at last after thinning out, they shall stand 

 36 or 40 feet apart. 



The sugar maple and American elm are the most valuable trees for roadside 

 planting, but they are both rather slow growers, and for 20 years will not make 

 a very complete line of shade unless closely planted. For the purpose of 

 getting more immediate effect it would be well to plant these trees 36 or 40 feet 

 apart and alternate them with the silver leafed maple, Acer dasycarpum, which 

 is well adapted to this purpose, having a good broad foliage, a spreading head, 

 and is a rapid grower. In 15 or 20 years after planting the silver maples should 

 be cut out and the elms or hard maples allowed the full room. By adopting this 

 method of planting, a satisfactory amount of shade may be attained in the 

 shortest time. Such desirable trees as the American elm and the hard maple will 

 ultimately line the street. And they will then stand sufficiently far apart for 

 their full development. 



RETURNS FROM TREE PLANTING. 



One rainy day I drove two miles and dug, unaided, a load of sugar maples 

 and planted them along the roadside. They are now beautiful trees, nearly a 

 foot in diameter, and no sane proprietor would think of parting with one for 

 825. Here is an easy way to make money and build a monument for yourself. 

 This load of trees cost me one day's work. I claim that an avenue of maples 

 or elms on the highway is often worth to the farm from $500 to $1,000, and 

 that many farms will sell for that much more with such trees than without 

 them. They need not be set nearer together than 100 feet, alternating on 

 opposite sides so that no two trees are opposite. The elm is our most durable 

 tree and one of the most attractive. — 0. A. Green. 



TIMBER PLANTING. 



THE BLACK WALNUT. 



"While there is a great deal of loose talk about the danger of the United 

 States being without a stick of timber within the near future, there is no doubt 

 but that it will pay now to plant some kinds of trees in some particular situa- 

 tions. There are yet millions of acres of American forests growing up or
