CHOICE BETWEEN THE VARIOUS SYSTEMS OF TRANSPORTATION 



(g) Maximum weight and size, also average, 

 weight and size of pieces to be handled ; 



(h) Price and effect ofday labor and prospects 

 of changing prices under the influence of 

 labor laws and socialistic legislation; 



(i) Relative price of team labor and of man- 

 ual labor; 



( j ) Condition of existing public means of 

 transportation; roads, railroads, and navi- 

 gable rivers; 



(k) Laws relative to rights of way and relat- 

 ive to damage inflicted on outsiders in 

 the course of transportation, e. g., by 

 splashing logs or by raising water level 

 of lakes and thus destroying trees, &c. ; 



( i ) Mileage of the various links forming the 

 chain of transportation and speculation as

(m) Silvicultural considerations, or choice between conservative and destructive lumbering. Steam skid- 

 ding on the ground is the destroyer of a second growth intended to be left. High two -wheel logging 

 carts can be used advantageously to save a young growth; 



(n) Possibility and amount of damage to logs and loss of logs in course of transportation. Loss of 

 bark. Loss of sapwood. Deterioration by fungi and insects. Theft. Loss of interest on value of logs; 



(o) Regularity and reliability of means of transportation; 



(p) Possibility of using the means of transportation for purposes other than carrying forest products (access 

 to mines and farms; passenger traffic; supplies for lumber camps; use of snaking roads as fire lanes, 

 patrol trails, sport trails); 



(q) The general political and economic condition of the country (settled or unsettled); the possibility of 

 financial surprises.
