TREES FOR TOWNS.

To these may be added some climbing plants: —

 space of a square or a crescent will admit of their 

 being grouped, necessarily follow the lines of

the streets, and constitute avenues, single or 

 double, according to the available space. It is 

 important that in these cases the avenues, or at 

 least the corresponding lines on each side of the 

 street, should consist of one kind of tree, other- 

 wise the effect is not satisfactory. 



In all cases good preparation should be made 

 for the roots. Openings 6 or 7 feet across, 

 and at least 3 feet deep, should be made, and 

 filled in with good new soil, unless in the case 

 of new lines of streets, where the ground is 

 good, or has been made up with a mixture of 

 earth of fair quality and such open material as 

 brick rubble. Then, indeed, a smaller quantity 

 of new soil may suffice to give the trees a start; 

 but in all other cases there should be no stint 

 of good fresh soil at the outset. The surface 

 should be thoroughly mulched after planting 

 the trees, if it can possibly be done, and the 

 stems should without delay be protected by 

 means of circular tree-guards (fig. 415). If these 

 are not necessary a stout stake, preferably oak 

 with the base soaked in creosote, should be
