three months, or until the tree has got a good start, then twice 

 a week, and later once a week, as the roots go deeper into the 

 soil. It should be remembered that the more careful the atten- 

 tion is that can be given to the tree, the more likely is it to be- 

 come established as a vigorous and thrifty specimen. 



Protection of the Trees From Injury. 



Protection from strong winds in exposed places is necessary 

 until the tree gets well rooted in the soil. This may be done in 

 different ways. Probably the cheapest and easiest plan is to drive 

 in two stakes on the windward side of the tree about three feet 

 apart and to tie to them an old grain or sugar bag. One thickness 

 is enough. Where there is danger of injury from cattle or other 

 stock the young tree should be protected by some sort of a fence. 

 While the tree is small, stakes set about it are usually sufficient ; 

 as the tree grows larger an inexpensive frame work should be 

 built. 



Grass and weeds should, of course, be kept away from the tree 

 until it grows large enough to rise above them, when it will take 

 care of itself. 



Pruning and Care of Street Trees. 



This circular has outlined the different steps in connection with 

 the raising, planting and protecting of trees to be used for orna- 

 mental, shade and landscape purposes, but our work is not yet 

 finished if we are going to make our streets and highways assume 

 the appearance of some of the noted boulevards on the mainland 

 or the continent of Europe. Supposing a careful selection of the 

 trees t>est suited to the different streets and locations has been 

 made and the instructions regarding planting, etc., have been car- 

 ried out, constant care will be required to keep the trees in good 

 shape until the crown or leaf canopy gets out of the reach of 

 animals and the small boy. Pruning will have to be frequently 

 done to keep the trees of a uniform shape and to make each tree 

 look exactly like its next neighbor. 



; All the trees along both sides of a street or highway should be 

 of the same species for a unit of distance, which should be at
