The empties return, being pulled up by the descending load and 

 passing by on a switch placed half way. Sidelines with 2 to 4% 

 grade operated by man power bring the wood to the main track. 

 Such a system with about 8 miles of side lines to build had cost 

 about ^9000. The total investment cost on the 3,000,000 cubic 

 feet (about 12 million feet B.M. and 5600 cords) being about 45 

 cents per 100 cubic feet (or 62 cents per M ft. B.M. and 28 cents 

 per cord). The cost of moving was less than 10 cents per 100 

 cubic feet (20 cents per M ft. and 9 cents per cord). Parts having 

 been moved by slides, parts by hand sleds, a comparison of the 

 different methods showed the proportion of 183 : 168 : 120 re- 

 spectively for slides, rail (including amortization) and hand sled. 

 The last method was the cheapest but as it could not be used 

 until the following winter a considerable deterioration of quality 

 was experienced which was estimated at nearly 12 cents per 

 100 cubic feet.

Weight, shrinkage and use of the different 

 Timber Physics Japanese woods have been investigated by 

 of Kitao Moroto, a member of the Japanese 



Japanese Woods. Forest Service. The results are only of 

 preliminary value, preceding a more ex- 

 tensive investigation. Of interest to us is perhaps the enumera- 

 tion of species for different uses. The building timber is i^xx■n.' 

 is\\e:(X hy Cryptojneria /ap07iica, Chamaecyparis obttisa, Thiiyopsis 

 dolobrata, and Abies Sachalinensis, besides Pinics densiflora and 

 Thunbergii. Zelkova which was formerly considered indispens- 

 able for large buildings has, like our White Pine, become too 

 scarce and expensive. A number of oaks furnish carriage 

 material, while this class of wood does not .seem to be used for 

 ■cooperage, which relies on the three first mentioned of the cedar 

 tribe with Chamaecyparis pisifera added. For packing boxes 

 several species of Abies, Pimis and Picea with the all-important 

 Cryptomeria is used. Joinery material is furnished by the first 

 two mentioned cedars, and in addition by Pauloumia tomentosa, 

 Thitja Japonica, Taxjcs ctispidata 2in<l, for clothes chests, Cirma- 

 momum Camphora. Small lacquered woodenware is made from 

 Chamaecyparis and Thiiyopsis in addition to Mag7iolia hypoteiica,
