large trees, which has worked well. It is fitted on a 9-inch by 

 3-inch frame, swung on i-inch bolts at one end and raised or 

 lowered at the other end by a long -|-inch screw and hand-wheel 

 to suit the size of the bottom saw, and fixed firmly with strap 

 plates and bolts when correctly set. The top saw has to be set 

 exactly in the same vertical plane as the bottom one, and 



2 inches to the right, so as to allow the saws to overlap about 

 half an inch. 



The arrangement has proved to be a great saver of time and 

 wood. Before we used it we had often to cross-cut good Scots 

 pine (equal to first quality yellow pine) into stob lengths, run 

 the 4-feet saw through, sometimes twisting a newly-hammered 

 saw in the process, and split off the top unsawn portion, wasting 

 a lot of good wood when doing so. We can now cut up to 



3 ft. 6 ins. quickly and accurately, without injuring the temper 

 of either saws or men, providing the saws are properly set and 

 sharpened. As the top saw runs without guides, it has to be 

 extra heavy. I got one specially made for it, 2 ft. 6 ins. in 

 diameter. No. 8 B.W.G., 3-inch pitch, |-inch rake. The photo 

 shows a 3 ft. 6 ins. saw at the bottom, instead of the 4 feet 

 which is used for large trees. The top saw can be lowered to 

 suit this saw also.

Notes on Scots Pine. 



The following notes of some Scots pine trees recently sold 

 may be of interest to some readers of the Transactions : — 



The average cubic contents of the trees, carefully taken, were 

 100 ft. 7 ins. The average total height was 75 feet, with the 

 tallest tree measuring 85 ft. 3 ins. The percentage of clean butt 

 was 55, and this was sold to a firm of timber merchants at 

 2S. 9d. per foot on rail, with an allowance of 10 per cent, for 

 bark. The cost of felling, snedding, cross-cutting, and burning 

 brush was 2d. per foot on the whole, and the cost of putting the 

 butts on rail was 3d. per foot on the material sold. The weight 

 of the timber came out at 28 cubic feet to the ton. A small 

 portion of the timber, after being manufactured, was purchased 

 by a contractor in the district in which it was grown, and the 

 buyer states he never had finer material.
