IN this, our latest design of Shingle Machine, we have incorporated all the advantages contain- ed in our wood frame 'Simplex" and added several improvements. The arbor has been made heavier and a third bearing added to support it outside the driving pulley. The method of putting lead in the saw arbor has been greatly improved. This is now done by swinging on a centre directly under the saw the whole frame which carries the arbor. Thus the alignment of the bearings is not in any way affected and there will be no danger of hot bearings after the lead has been changed. The change may be made while the machine is running and without stopping the carriage. An improvement has also been made in the method of driving the edger. It is belted direct from a shaft running at right angles to the main arbor from which it is driven by means of a bevel friction. This m .kes a very neat compact drive and has proved satisfactory in the mill. The rail on which the carriage travels is made of square steel and when worn can be renewed by simply turning upside down. Over three hundred of our Upright Machines (wood and iron frames) are in use in British Columbia and Washington. MANUFACTURED ONLY BY Letson <fc Burpee, Limited, Vancouver, B. C "THE DUNBAR 99 STEAM New and Improved LOGGING ENGINES. This is the machine for which we claim all the good Qualities possessed by any other and a great many valuable improvements besides. Best on the Market This time we wish to call your attention to one of many important points which prove conclusively the superiority of the Dunbar Logging Engines: that of the Hydraulic Apparatus foi raising and lowering the Boiler, an invention of our Mr. Dunbar, Sr. (for which patents are pending). By this device all danger from rush of water to either end of the Boiler, caused by irregularities of the road, is avoided. One o
