144 FORESTRY IN LITHUANIA. 



portation of forest materials of more minute workmanship, 

 such as rakes, a more careful packing is required, and 

 more care must be taken during transportation. The 

 products of wood technically prepared particularly require 

 more costly packing, and therefore their transport is 

 much more expensive than other forest materials, particu- 

 larly such as require the least care in transport, and there- 

 fore the land carriage per pood is cheaper. On these 

 considerations we think that previous to making an estimate 

 we must ascertain the weight of each sort of forest materials, 

 and the number of horse carts required for the trans- 

 port of this assortment, if it be of large dimensions; and if 

 of small dimensions, then in the number of pieces of this 

 assortment that can be placed on one cart. The chief 

 foundations for such estimates are the following: The 

 weight of a cubic foot of wood, the cubic contents of one 

 or other assortment of materials, and the normal strength 

 of a peasant's horse. These are of course known, but hitherto 

 have scarcely been taken into account in estimates. In 

 making the following table we have had in view to give a 

 foundation for such calculations requisite in each case. With 

 regard to the cubic contents (shown lower in the table), in 

 most cases the medium for the three dimensions should be 

 increased a little if it can be foreseen that an unequal 

 number of different dimensions, and principally great, will 

 be received ; in the contrary case they should be lessened. 

 ' With this calculation the weight of a cubic foot for 

 coniferous and soft leaved kinds in a half-dry state has been 

 considered 40 lb., and for the hard leaved sort, in the half- 

 dry state, at 60 lb ; for soaked timber (floated) on landing 

 it a quarter more should be added to the weight.
