tables given in the Woodsman Handbook, I find it corresponds 

 very closely to the Baxter Rule. For logs over 20" in diameter, 

 the contents of logs given is slightly less than in the Baxter Rule. 

 By applying Prof. Daniel's Method given on page 34 of Graves' 

 Forest Mensuration, we find the formulae for this table to be 

 V=f D^-f 9/20 D— 7. 



According to Mr. Wm. Younglove, his father would never im- 

 part the secret of making this to anyone, and often boasted that 

 it would die with him. Since his death, there have been no 

 more Younglove Calipers made, and I believe at the present 

 time I have in my possession the last one ever placed on the mar- 

 ket for sale. From those who have used this rule, I find that 

 the best results are obtained from taking the diameter outside 

 the bark at the small end of the log. I have used the caliper 

 myself this year in measuring logs, cut from a small woodlot 

 near by, and have taken measurements both at the small end, 

 and one third of the way from the small end. These logs have 

 been marked and I hope to follow them through the mill at some 

 later date to see which measurements tally up the best. 



It would seem that the table would give very fair results for 

 the measurement of small diameters but runs rather low for dia- 

 meters above 24 inches.

 of practical interest. — Ed.)
