SHADE TREES. 



widths uniform spacing is sometimes difficult, but there is 

 no need to place trees in the same position in front of every 

 house. 



Spacing. Do not plant trees so close together that when 

 grown they will interfere or entirely shade the house fronts. 

 Too much shade is as bad as too little, and each tree should 

 have room to develop its own form. (Fig. 4.) In blocks 

 made up of lots 20 feet wide, or less, a tree should be planted 

 in front of every other house only, those on opposite sides 

 being alternated thus : 



Fig. 5. How trees should be placed on a narrow street. 



On wider streets, 40 feet, 50 feet, 60 feet or even more 

 may be given to a tree according to its size and habit of 

 growth, and the arrangement may be opposite or alternate ac- 

 cording to conditions. But in every case the aim should be to 

 develop rows, or blocks, of trees, rather than individuals. A 

 quick effect can be secured by planting trees closely, and as 

 they grow removing the alternate ones. But a very practical 

 difficulty, apart from the cost, is that no one wants to thin 

 them out at the proper time. If close planting is resorted 

 to the intervals must ~be half or one-third the intended ulti- 

 mate spacing.
