the size of a cart wheel to some men, while to others only that of 

 a tin plate. So be careful of your lengths and diameters. 



Never scale a log above or just at the crotch, because it gives 

 you a larger diameter; the length and top end give you amount 

 of board feet in your log. The Doyle rule on small logs takes too 

 many for a thousand feet, while on large logs the scale is so close 

 they will barely squeeze through the mill. So be careful in using 

 this rule. The Holland or Penobscot rule gives you nearer what 

 you have in your log. 



You can estimate 4 to 6 miles some days and in some countries, 

 while other days and in other countries, one mile is a good day's 

 work. Conditions of travel and amount of timber determine num- 

 ber of miles cruised. 



Never trust to your memory in writing in your notes or at what 

 point on your line the growth changed. At whatever point the 

 change takes place or you encounter anything which should be 

 noted, stop at that point and record it. 



Keep your notes and estimates up with your work each day. 



If you are an experienced cruiser and woodsman, and have for 

 a companion a young man just out on his first real work from some 

 school of forestry, don't laugh at the many new and seemingly 

 foolish theories he has in his head. You can teach him more in one 

 week about the real work in hand than he learned in all the years 

 he was in school. If he has the right timber in him, of which 

 woodsmen are made, he'll be grateful to you and think you are 

 "Big Medicine." Talk to him and use him like a man and you'll 

 learn some things from him you never dreamed of. 



If you get lost, keep as cool-headed as you can. Don't run 

 around. Sit down and talk it over with yourself. Give signals of 

 distress and keep a good fire going at night. 



PREPARING FOR A CRUISE 

 Never, if avoidable, go on a cruise in a rush. Make careful 

 preparations and use good sound judgment in selecting your outfit. 

 First, if possible, find out into what part of the country you are go- 

 ing, and what transportation facilities you will have. If transpor-
