and other cities. In other instances pin oaks, arborvitae, etc., 

 that had been transplanted several years, and were thought to 

 be established, weakened, and some died, though many revived 

 after the rains of June and July. Many wild cedars on the 

 hillsides failed in the spring drougth, but in several ways the 

 most interesting, and alarming, case was that of the beeches. In 

 dry weather one of these trees will transpire really an immense 

 quantity of water. If that is not replaced by a sufficient supply 

 through a considerable depth of soil, leaf wilt appears and death 

 may follow. This situation caused much concern in the Essex 

 county parks and a few trees died, though most of them, have 

 set normal winter buds and are apparently safe. In other places, 

 including several private properties, valued trees were lost. 



TREE WOUNDS. 



So many people have been led to believe that the chief need 

 of a tree out of condition is to fill it full of cement that a word 

 on the subject of tree wounds and tree cavities is in place. It 

 will be understood that this is but one feature in tree culture. 



When the bark of a tree is broken, be it by accident or by 

 design, it is necessary to guard the exposed wood against decay. 

 The many diseased spots on our shade trees are due chiefly to 

 neglect of this precaution. If a limb is cut O'ff the stub should 

 be inimediately covered with tar or oil paint to prevent decay. 

 Where a serious wound has been suffered, or where decay has 

 set in, the best treatment in most cases is to clean the cavity and 

 expose a smooth surface of sound wood. Coat that with coal tar, 

 taking care not to touch the cambium the growing tissue be- 

 tween the wood and bark and leave the rest to< nature. Unless 

 the cavity be very large, or is so located that water will collect 

 in it, there is no need for a cement filling. Fig. 23 illustrates how 

 tree wounds are healed better with no treatment at all than when 

 cement is used where it is not needed.
