In running, the logs are run with the butt end first, being 

 " nosed " to two-thirds of their diameter, which not only makes 

 them run better, but saves the slide. At the end of the slide 

 the grade is reduced so that the logs arrive with less velocity, 

 and often several switches, worked by movable booms, are in- 

 troduced to assort the sizes. In order to be able to transport 

 fuel wood and small dimensions the slide might be adapted for 

 use as a sled road by keeping the grade between 15 and 25 % 

 and avoiding narrow curves.

A remarkable wire rope line of over 20 



Wire Rope mile length, Bleichert system, for carrying 



Tra?tsportation ore —it could carry logs as well — with an 



elevation of nearly 1 2,000 feet to overcome 

 has been for two years in operation in Argentina belonging to 

 the government It includes spans of 1500 to 2800 feet and 

 grades of 45°, the rope sometimes passing 1200 feet above ground. 

 The cars make the distance in four hours, carrying not only ore, 

 but building and other material, provisions, water, mail, and 

 passengers. In the mountain section the capacity per hour i& 

 90,000 lbs. in 80 cars running 360 feet or 45 seconds apart. In 

 the valley section the capacity is reduced to one-half. The line 

 is run in eight sections, worked from as many stations, each with 

 a separate rope, drums and engine. Gravity, of course, saves- 

 largely in the power needed. In spite of the difficulties of 

 locality, which required nearly 80 miles of road building, the 

 installation was effected by the German firm in 18 months. The 

 cost of transporting which formerly by mules, possible only 4 to- 

 5 months in the year, had been about $12 per ton, has been re- 

 duced to $1.35. Smaller such rope ways are in use in various 

 mountain districts,

The details of logging forty acres of long- 



Cheap leaf pine in Alabama illustrates the cheap- 



Logging ness at which the southern lumbermen can 



operate. A forty-acre tract in Calcasieu 



parish, representative of the best longleaf now standing, produced
