WHAT IS ^ City Forester Colton says it is worth $, and if uninjured by higli tension wires would be worth $ 15 per cent below a perfect tree. Therefore, if the value of a sugar maple was 64'/2 cents per square inch of cross-section, the value of a per- fect tree ,or a standard value, would be 75 cents. A table has been prepared, using 75 cents as the value per square inch of basal area for a perfect tree ,and showing the proper deduc- tion factors for all species of shade trees. This table is being used by this office in obtaining values, and has been found very satisfactory. There is one point in the discussion of the value of a shade tree which has not been touched upon in this article, and that is "loca- tion". Viewed from some angles, this is a very important point. From the fact, however, that there is such a chance for diversity of opinion as to the proper and improper location of a shade tree, I have purposely neglected to take this into consideration in my factors for deduc- tions. The opportunities for deductions of all kinds are so great ,and the possibility of arriv- ing at any definite figure for abatement so un- certain, that it has seemed best to eliminate this factor entirely. It is my belief that this deduction can safely be neglected, unless the tree is most obviously out of its proper location. If, as stated above, there can be no question about its improper location, then the party or parties judging the value should make some arbitrary reduction from the value placed on the tree by the prepared tables. As a concrete example for the usefulness of some set value for shade trees, we have estab- lished an approximate value for all the street trees of Newton, Massachusetts. In the summary of data gathered from the shade tree census, we have grouped all our trees by species, diameter classes and conditions. For inst
