Complete Assembly. Length over all, 18 ft. Length main channel frame, 14 ft. 6 in. mately $500 per day. The storm continues for possibly two days. As soon as it subsides, three or more teams are sent over the road with the plow, consisting of hewn timbers bolted together to form two spreading wings. The plow is weighted and dragged over the road, running the snow to a bank on both sides. The tanking teams follow behind the plow and with good luck and fine weather, in two or three days the teams are working well once more. The operator now has a good road with ample snow and is not praying for more, as a two days' storm can easily mean a loss of several hundred dol- lars to him. Snow storms, however, are common occurrences in our vigorous winter climate and storm follows storm until the operator must in- crease his force, or leave part of his cuts in the yards. The plow which he has been using no longer works satisfactorily, for, after a few trips over the road with it, the banks are formed so high that it is difficult to remove the snow out of the road. The road rapidly becomes high and difficulty is experienced with the heavy loads cut- ting out. A heavy rain means that the operations is tied up, until it freezes again with resultant delay and expense. The operator has long felt the necessity of a practical winter road- making machine. This need has led to the development of the rotary snow plow. This machine is a proven success in country highways and sub- urban work, and promises to have a great field in the maintenance of logging roads. The accompanying photographs show the machine at rest and in operation. The horses are not required to do very heavy work, as the mahine slides on runners and the front sled is high enough to clear a 24-inch bank of snow without dragging, if desired, the machine may be set to an offset on the front and rear sled, so that when cutting the bank away in widening the road, the horses travel on the part of the road already cleared. In one traverse the machine clears a space 5^ feet wide. The depth of it and the slope of its surface may be regulated by moving the rotary cutters as the machine passes along. Thus, the surface of the road can be made of uniform height. An uneven tilted surface can be levelled; or a 22-inch comb or ridge, 1 inch to 4 inches in height, can be left by centre plow adjustment. In two traverses (out and return) a road 11 feet wide can be cut, and this width can be increased by addi- tional traverses, the snow being thrown beyond the part already clear- ed. With this machine on a logging road the road could be main- tained 100 per cent, efficient at all times. If during a storm the operator would operate this plow ahead of his teams, he could haul as good a load as he could before the storm began. The snow thrown out of the road would never form a bank, and the road could be maintained with a good hard bottom at all times. The expense of tanking the road would be reduced at least 75 per cent. The water would be confined to the rut, formed by the rotarv cutters, in which the sled runners travel. If a good ice bottom were once secured, it could be maintained at a small expense, for, during the storm the rotary cutters on the plow could be set at the proper depth to remove only the snow down to the ice surface. With this machine a good iced road could be maintained without the expendi- ture of tanking the road after every snow flurry. One team of horses and two men on the Stadig plow could maintain a logging road so that full capacity loads could be hauled regardless of stormy weather. The saving to the operator would be great, and it would seem as if every operator must see the advantages to be gained. The Canadian Fairbanks-Morse Co. report that the Laurentide Co., Grand Mere, Que., and the Fraser Companies of Edmundston, N B., were among the first organizations to utilize these power snow plows for making roads. It was the intention of the manufacturers to demonstrate the rotary snow plow on the hauling roads of both the Laurentide and Fraser companies, but the machine which \va- held for this purpose was destroyed in a warehouse fire, and an- other one, not being available, the matter was dropped temporarily.
