has arisen owing to the limited nnmber of milkers now 
obtainable, and will also deal with the problem of the complete 
purification of milk. The process of milking by machine is 
certainly far more cleanly and hygienic than hand milking, 
and it is also claimed that recent improvements in the design 
of the machines have entirely prevented the possibility of 
injury to the cows. It is asserted that neither the quantity 
nor the quality of the milk yield is injuriously affected, and 
that the milking is thorough, while the cost of labour is reduced 
some 50 per cent. The cost of maintaining the machines in 
repair is said to be sliglit. 
Article 3877. — Messrs. A. Ransome <& Co., Ltd., Newark- 
on-Trent. “ Horizontal Log Band Saw (Ransome and Lavos 
Patent, with direct electric drive).” Price 700^. — The machine 
exhibited, size OA (Fig. 3), will deal with logs up to 48 inches 
in diameter. It is driven by a 50 horse-power electric motor.

and the feed and elevating gear is actuated by a second 12 
horse-power motor. The saw is .5^ in. wide, by No. 18 gauge, 
and the teeth are 1^ in. pitch, the pulleys being 5 ft. in 
diameter. For forest use, one of the great advantages of these 
saws is that they are entirely above ground, and only a small 
concrete foundation is required. The saw blade runs at a speed 
of 7,000 ft. a minute, and the saw pulleys are fitted on turned 
steel shafts running in ball bearings. By the movement of a 
weight on a hoi’izontal lever the tension of the blade is varied 
to suit saws of different gauges. The feed ranges from 4 to 
80 ft. a minute, and is controlled by a switch handle, by 
which the advance of the log can be instantaneously regulated.
