UTILIZATION, MARKET AND TECHNOLOGY. 



H. W. Glover of the Indian Service de- 

 Trattsport scribes in detail a local method of trans- 



by Aerial ^x)rting fuel at Murree in the Himalaya 



Cable. Mountains. The ropeway is three miles 



in length and the loading station is situated 

 at an elevation of 6,387 feet, the unloading station at an eleva- 

 tion of 6,567 feet, with the lowest intermediate point 5,454 feet. 

 An endless wire cable, which passes around horizontal wheels, 

 is suspended at intervals along its course on sheaves supported 

 by trestkh and steel beams which rest on concrete foundations. 

 Detailed drawings and figures accompany the description. A 

 very detailed estimate of cost of construction and operating ex- 

 pense is appended.

Prices for mine timbers increased in 

 Prices 191 3 over 1914 by from 5 to 10 per cent, 



of Wood and in some cases up to 31 per cent, due 



in to increased demand and decreased im- 



Prussia. portation. Railroad ties (2-15%) and 



pulpwood also brought substantial in- 

 creases (2-6%.) On the other hand, the market for sawmill 

 products was poor or at least uncertain, although in South Ger- 

 many conditions were more favorable, the imports there play- 

 ing an important role, and these have become more expensive, 

 due to increased cost of production in the export countries. In 

 general, i to 4 per cent may be considered the average increase 

 in wood prices for the year.

By 1909 the German railroads had over

Baden, while Saxony was almost without 



metal ties. At first 88 lb. ties were used, which did not last 



more than 15 years; then 118 lb. ties, and finally 154 lb. ties'
