1. Correct way of removing a small branch A, or a large branch B. No 



stub should be left 23 



2. Wrong way of cutting a small branch A, or a large branch B, where 



a stub is left. Such stubs die and produce hollows 33 



3. In pruning large branches, especially on trees which are past their 



youth, and whose powers of sprouting from cut branches is re- 

 duced, they should be pruned so as to leave a living branch grow- 

 ing from the end of the stub. This branch will usually maintain 

 sufficient growth in the stub to cause the healing of the wound 

 where the large branch was removed 24 



4. Hollow snags should be cut close to the live branch from which they 



spring, as at AB. If the hollow penetrates the live branch it 

 should either be filled with cement or with a wooden plug and 

 painted, after the snag is removed 24 



5. Since there is danger of large limbs splitting and tearing the bark 



loose from the tree, it is preferable to cut them twice. AB 

 shows the position of the first cut, an undercut being first made 

 with a hatchet, the branch then sawed off from above. The stub 

 is then sawed off smoothly at CD as close as possible to the line 

 of sap flow 25 



6. Skeleton saw, pruning saw, with tapering frame, for use in narrow 



space. For hand use 26 



7. Pruning saw for heavy work 27 



8. Pruning hook and saw. Can be used either with or without pole. 



Saw blade is quickly removed and the pole shears can be used 

 alone. Shears can also be secured without the saw 27 



9. Adjustable pole pruning saw. Adapted for sawing by hand or at- 



tached to a pole. The handle, which has a socket for use with 

 pole, is adjustable for convenience of using at different angles. 

 Blade 18 inches long 27 



10. Street 65 feet wide. Single row of trees in middle. Ornamental 



trees can be alternated with standard shade trees 34 



11. Street 60 feet wide. Single lateral row of trees on each side, either 



standard shade trees; or standard shade trees alternating with 

 ornamental trees, or with broad leaf evergreen trees 34 



12. Street 100 feet wide. Single lateral rows and single middle row. 



Ornamental trees or ornamental trees alternating with the same 

 standard shade trees used on the lateral rows can be planted in 

 the middle row 34 



13. Street 100 feet wide. Double lateral rows, the trees in the rows 



arranged quincunxially or alternately 34 



14. Alternate planting 34 



15. Opposite planting 34 



16. Street 125 feet wide. Two lateral rows of trees arranged alternately, 



one row of standard shade trees, the other of ornamental trees. . 36
