96 Practical Forestry 



extent around the stem and avoid planting too deeply ; 

 the nursery mark on the stem serves as the best guide 

 as to the depth at which to plant. Planting too deeply 

 under the mistaken idea that doing so will secure the 

 tree in the ground is a fruitful source of decay and ultimate 

 death of many street trees planted in the metropolis, and 

 it is not uncommon to see whole avenues of trees that have 

 made little or no progress for many years owing to this 

 cause. After a tree has been placed in an upright position 

 on the prepared site and the roots properly disposed, the 

 soil should be filled in and trampled firmly both amongst 

 and over the roots. It may be well to warn planters 

 against the pernicious practice of allowing leaves, packing 

 materials, or grassy turf to come in contact with the roots 

 of newly- planted trees. In dry situations a saucer-shaped 

 hollow may be left around the stem of the newly- planted 

 tree, while mulching applied during dry and warm summers 

 is to be recommended. The planting of shrubs should be 

 carried out with as much care as is used in the case of trees. 

 It is preferable to trench land in which shrubs are to be 

 planted rather than to make a separate pit for each 

 shrub. 



Street trees should be carefully matched that is, those 

 of similar height and shape used in the same street. Too 

 often this principle is not observed, as in a new street near 

 the Strand, where some of the specimens are about 10 ft. 

 high, others, 15 ft. and 20 ft. high forming a very irregular, 

 badly matched row. Many newly -planted town trees are 

 destitute of leading shoots and have ungainly side branches 

 faults that should never be permitted when choosing speci- 

 mens for such an important purpose. In choosing trees 

 for street planting, the following rules should be observed : 



1. Stout, healthy, well-rooted and recently transplanted 

 trees should alone be chosen. 



2. They should, for the same street, be of nearly equal 

 height and branch spread. 



3. Straight-stemmed trees, with stout leading shoots, are 

 to be preferred. 



4. The height should range from, say, 12 ft. to 14 ft. or
