The ordinary form of log-boom, so familiar on the Pacific coast, is liable to be broken up and the logs lost, if the boom should be unfortunate enough to meet rough weather while m tow. Even in the comparatively sheltered waters along the coast large and valuable booms of logs are fre- quently lost, but the risk is consider- ably greater where the boom is to be towed through more exposed waters, where it is not unusual for the tow to go adrift, or a large portion of the logs escape with but small chances for recovery. The losses from this cause have run into large figures annually and the risk from certain localities has been too great to permit the develop- ment of some valuable timber limits. The new system of log-rafting patented by G. G. Davis, of Van- couver, is creating increasing interest among the loggers and mill men in British Columbia. The illustration reproduced here- with will give an idea of the principles of the new system. This form of rafting may be constructed at a cost of 12c to 35c per M., depending on the locality and kind of timber. The percentage of loss in this system has been extremely low, while in the old method the loss in exposed w^aters, such as the west coast of Vancouver Island, has occasionally been as high as 50 per cent. There was one Davis raft lost in Queen Charlotte Sound, the weather and sea having become so rough that the tug boat had to cut clear and run for shelter. This raft was last seen by a Japanese liner over 2000 miles at sea and still intact. Among other records of the success of this system is that of towing 30,000 feet of logs from Ocean Falls to Puget Sound, a distance of over 500 miles, without anv loss whatever. What the forest fire thieves in one year would pay the premiums on S1,000 life insurance for 300,000 Can- adians at 25 years of age. It would almost double t
