certain species to conditions, since the cost of preparing suitable 

 conditions is too often beyond the funds allowed for this purpose in 

 most towns. Mr. John A. Pettigrew, Superintendent of the Boston 

 parks, says that it is safe to say that if one has twenty dollars to 

 spend on planting a street tree, nine-tenths of it should be spent on 

 the preparation of the ground. 



Olmsted Bros., landscape gardeners, in one of their reports to an 

 association with limited funds, says in regard to the planting of 

 elms : 



" It would be better to prepare tree beds two to three feet deep 

 and twenty to thirty feet square, filled with good loamy soil where 

 the present ground is dry and sandy gravel, even if the expense of 

 doing so would be so great that only one tree a year could be 

 planted." Few trees, however, outside of those planted in the Ar- 

 nold Arboretum and on a few private estates receive any such treat- 

 ment, but it is hoped that much more attention will be given to good 

 planting in the future. The majority of street trees which are planted 

 are not supplied with loam or placed in holes over three feet wide 

 and fifteen inches deep. A hole six feet wide by twenty inches deep 

 in any case should be the smallest used, and it should be as much 

 larger as can be afforded. 



When digging up young trees the roots should be preserved as 

 much as possible and the more earth that can be taken up with the 

 roots the better. The roots should not be exposed to the sun and 

 wind, and if possible they should be kept covered and moist, for 

 which purpose damp straw, bagging or sphagnum moss may be used. 



It is usually the practice to place the best side of the tree toward 

 the north and the poorest toward the south, since the light conditions 

 on the south side are better and naturally better growth results. It 

 is also advisable to lean a tree toward the direction of the prevailing 

 winds, and if these are strong enough to interfere with the growth of 

 the tree it should be fastened to a strong stake. 



When the ground is prepared for planting the injured roots should 

 be pruned so that healing may take place, and before being covered 

 they should be properly arranged in the soil. According to good 

 authorities trees should never be planted more than two or three 

 inches deeper than they originally grew. It is more convenient for 

 two men to set out a tree than one, as one can hold the tree in its 

 proper position while the other is filling the soil in around the roots.
