CANADA LUMBERMAN AND WOODWORKER 29 B. C. Timbers for Scow Construction Interesting Equipment for Laying Toronto's In- take Pipe—Canadian Materials used Throughout In these days when one hears so much complaint about the extent to which southern pine is taking the place of Canadian lumber and timbers in the markets of Canada it is refreshing to learn of cases in which Canadian timber is the only kind which a contractor will use for a special purpose. Such an occurrence is so rare that it is worthy of special note and we are pleased for this reason to re- produce a picture of some timbers which have been used in Toronto in the construction of a special class of scow which is to be used by Roger Miller & Sons, contractors, for the work of laving the intake pipe for the city of Toronto. The only timber used "in "these scows is British Columbia fir which was obtained from the firm of Mason, Gordon & Company, Montreal. The scows are 100 feet long, 30 feet wide and 8 feet deep. The Another interesting feature in which long British Columbia tim- bers come into play, is the provision which is made for propping the scows 011 bottom when it is necessary to do any heavy lifting. Two spud guides have been placed on one side of the scows and spuds consisting of 38-ft. timbers are lowered through them and allowed to rest upon the bottom of the lake while the lifting opera- tions are in progress. By this means good leverage is secured. In the construction of the scows all the boring and driving was done by compressed air as in most cases the awkward position and lack of light made it practically impossible to use anything in the nature of a hammer or hand drill. One of the scows is provided with two derricks, each of 20-ton capacity with clam shells for digging. The booms for the derricks are 14 in. x 16 in. x 65 ft. These derricks will be used for digging the trenches in which the pipes will be laid. The other scow will have a steel derrick of 20-ton capacity, which will be used for laying the pipes. The pipes are each 66 feet long and 6 feet in diameter and weigh 50 tons.

largest timbers used are the outside kelsons, which are 16 in. x 17 in. x 72 feet. In shipping these timbers from the coast to Toronto it was necessary to place them upon two flat cars on account of their great length. The side planks are also unusually large timbers, be- ing 5 in. thick, 21 in. wide and some of them 60 feet long. An inter- esting feature of these scows is the fact that they have each two bulk- heads at the sides. The timbers used for the bulkhead walls are 5 in. thick and run the whole length of the scows. By the use of valves placed in the side of the scow to admit water it is possible to dump the scows from either side. This is an extremely valuable feature, making it possible to dump heavy loads of rock at any desired spot at a trifling cost. The bulkheads are emptied by a pump after the dumping process has been completed. Another interesting feature in the construction of the scows is that each has three sets of two wells formed of 8 in. pipe. Two wells are placed in the centre and two others at each side of the scow. These wells extend from the top to the bottom of the scow and through them chains are passed which can be drawn up around the sections of intake pipe which are thus carried to the place where they are to be laid. The pipes can be lowered to their position with ease. Texas Northern Land and Irrigation Company Limited has been incorporated with a capital stock of $10,000,000 to acquire and hold timber lands, sink wells and construct waterworks, reservoirs, and develop powers for electric lighting and other purposes. The head office is at Toronto and the incorporators are Robt. Gowans, J. S. Lovell and Wm. Bain, all of Toronto. Reforesting- in Hastings County As a result of the act passed by the Ontario Government last year empowering municipalities to engage in forestry, the county of Hastings has already taken steps to acquire waste lands for the purpose of reforesting them. During the coming summer the Do- minion Commission of Conservation will supervise a survey of the county of Haliburton and the northern portion of the county of Peterborough. This survey is to furnish a detailed description of economic and natural conditions and resources of the watershed in Peterborough and Haliburton counties feeding the Trent Canal wa- ters, and to serve as a basis for a system of management.
