Book Description
Excerpt from Technical Publication No; 10, Vol. 18: Of the New York State College of Forestry at Syracuse University N. Y. He was persuaded to return immediately and to ship to the laboratory a liberal amount of material showing as great a variety of conditions as possible. On account of the fact that the infested larch was at a considerable distance from Syracuse (about one hundred and thirty-one miles) the ideal method of procedure in such studies - which should consist of field work and insectary work so coordinated as to check each other and to give the best results - were necessarily modified. The field work was reduced to a minimum and all field observations were made by the junior author at such odd times as opportunity offered. However, the work was so planned and conducted that the results obtained were in no way weakened. In fact, in a study of this sort the field work aside from the actual collecting of the infested wood, can be dispensed with much more readily than the insectary work; which, on the other hand, is indispensable because of the impossibility in the present state of our knowledge of identifying the immature stages of many boring insects.
