The top or green portion of the tree should always be maintained not less than one-half to one-third of the total height of the tree. If too little top is left the growth of the tree is seriously retarded. No more green branches are removed after the trunk has been cleared to the height of 19 feet above the ground, since the object is to produce only one sound clear 18 foot log per tree above the one foot allowed for stump height. The branches above the 19 foot mark are left to flourish and extend as they will, until such time as the trunk may have reached the diameter required by the owner and the tree is finally cut down. The Cost Per Tree, This is a simple method of obtain- ing good material from trees which would otherwise produce little better than fence posts or firewood. It is not a costly method when one con- siders that the work can be done dur- ing the winter when there is com- paratively little work being done on the farm. The total value of the labor when the pruning has been completed would probably not am- ount to more than 10 to 15 cents per tree. Removing the branches above the nineteen foot mark is not recom- mended largely because it necessi- tates a ladder of such length and weight being used, that it cannot be readily handled by one man. An- other reason for not removing the green branches above the first log length is the fact that the greater the green, top a tree has the more rapid is its trunk diameter growth. To reduce the size of the top further would mean the lengthening of the time required to produce merchant- able sized material. Lumber For Belgium. Professor Albert van Hecke, of the University of Louvain, Louvain, Bel- gium, is in America to study the most suitable lumber for the re-building of Belgium after the SPRUCE AND BALSAM COMING IN
