the purpose of shade, and produce nuts 

 as well. 



in Europe, fruit trees are planted 

 along the public roadways and some 

 have advocated their use in American 

 cities, but w^e consider this as a chim- 

 erical idea for the this country. The 



trees w^ould quickly be mutilated by 

 uncontrolled persons, while in Europe 

 the very strict laws and numerous 

 police officers; this can be prevented. 

 Still we have no objection to having 

 nut trees under control of the lot or 

 land owners. 



Distance For Planting Street Trees. 



Go to the forest, see the form assumed 

 by trees under crowded conditions, then 

 to the open field and observe the broad 

 spreading and shady trees of the same 

 species. It will be seen that ample 

 space must be given if an ideal tree is 

 to be produced. 



Then examine the monstrosities along 

 the streets of numerous cities and tow^ns 

 w^here the unhealthy tree trunks have 

 been crowded out of shape, have be- 

 come diseased, broken of limbs and de- 

 caying at heart. All because people 

 plant trees too closely and fail to thin 

 out in time. 



Twenty-five feet is not a great length 

 for a prominent branch in a full grow^n 

 tree, and few^ trees can form a perfect 

 shape with less length of branches. 



Thus forty to fifty feet should be the 

 distance between spreading trees and 

 thirty feet the nearest distance with up- 

 right growling trees. 



Yet ten to twelve feet is the general 

 rule, with resulting ill-shaped trees all 

 injured by those adjoining. 



Objection is made that it requires too 

 long a period for young trees to grow^ 

 into shade trees at such distances. 



Then plant some less valuable tree 

 w^hich w^ill grow^ more quickly, half w^ay 

 between the permanent trees, being sure 

 to remdve the temporary trees before 

 they destroy the form and character of 

 the more valuable, if slower growing 

 neighbors.
