SLEDS AND SLED-HAULING 1 59 



binding on the logs. It is adapted for hauls under three-fourths 

 of a mile where the distance is too great for snaking. 



From ten to sixteen logs may be hauled at one time on favor- 

 able grades. 



THE "jumbo" 



The jumbo, a modification of the go-devil, is used on a snow 

 haul in the Lake States, for distances not exceeding |-mile, where 

 the conditions do not warrant the use of heavy sleds. 



It consists of twin-sleds, similar in construction to go-devils, 

 joined together by cross-chains, with a distance between bunks 

 of about 9 feet. The runners are 8 feet long and have a 6|-foot 

 to 7 -foot gauge. Two go-devils may be fastened together and 

 used instead of special sleds. The jumbo will carry from 1000 

 to 1500 feet, log scale. 



Roads must be cut out, stumps removed and swamps cordu- 

 royed, but the cost of road construction is less than for two-sleds. 



THE TWO-SLED 



The transportation of logs from the skidway to a landing on 

 streams, to a railroad or to a mill is often effected by means of 

 a heavy sled called the "two-sled," "twin-sled" or "wagon- 

 sled." The gauge of sleds and minor features of construction 

 vary with the weight of the loads, length of logs that are to be 

 hauled and also with the ideas of the individual foremen, the 

 essential features, however, being similar. Some prefer a wide 

 gauge sled since the horses do not walk in the runner tracks and 

 the latter can be kept free from manure. 



A sled used on a Maine operation had runners io| feet long, 

 4 inches broad, 7 inches high, which were shod with flat 4-inch 

 steel shoes. The gauge was 5I feet. The runners were braced 

 near the center by a transverse bar called a bunk, which was 

 fastened to them by a wrought-iron casting, called a "dexter" 

 or "sled knee." A rocker rested on the bunk of the forward sled. 

 This rocker could turn around a king-pin that passed through 

 it and the bunk. The forward runners were also strengthened 

 by a flat roller rounded on the ends and fitted in circular holes in 

 the sled noses. To this roller the sled tongue was mortised.
