Amount of gasoline, 15 gallons. The above figures were taken several years ago when the facilities for unloading were slower than the present day methods, which accounts for the excessive length of time taken to unload.[8] [8] The writer is indebted to Mr. George Gunn, Jr., for these figures. The unloading of a truck is a time when a little care taken will save considerable expense for repairs. Such a method as the parbuckling system should be used by companies with sufficient stumpage to warrant the expense of the extra donkey, to prevent the top logs from dropping to the log bunks, thereby saving the cost of repairing broken springs and bearings. CONCLUSION At present, the possibilities for the use of the motor truck for logging are just beginning to be realized. What effect their use will have upon the future methods of logging remains to be seen. It is certain, however, that the advent of motor truck transportation will have a marked effect upon the science of forestry and will bring about a closer utilization of our timber resources. The motor truck and the portable band mill seem likely to furnish a combination which will do away with the old wasteful circular mill because it supplies the cheapness and efficiency of railroad transportation and is applicable to small and scattered tracts and to stands of low-grade lumber. The fact that the portable band mill may be moved for a cut of a million feet assures adaptability. This is not only an industrial advance but also a silvicultural advance in that it affords the possibility of cuttings at frequent intervals without greatly adding to the cost.
