has a high moisture content this quantity would make about 15 000 tons of 

 mechanical pulp or 10 000 of chemical pulp, which is nearly enough to 

 tide over the crisis that the war has caused in the paper trade. It does 

 not seem possible to work these 122 500 acres in an intensive manner all 

 at once, and it is suggested that the working of the Aran valley, mentioned 

 above should be continued; the 39 000 cubic yards of wood obtained would be 

 equivalent to 6 000 tons of mechanical pulp or 4 000 tons of chemical pulp. 



The remainder could be provided by the pine forests [Pinus sylvestris) 

 of Soria, Burgos, Sierra Carpetana and Cuenca. The vSpanish pine wood 

 contains more resin than that from the Baltic and Sweden and consequently 

 is less suitable for paper manufacture. Nevertheless this species occurs 

 at various altitudes, and it is probable that Piniis sylvestris from the dense 

 woods of the higher parts of the country closely resembles that from Nor- 

 thern Europe. 



The conclusion is drawn that the problem of providing raw material 

 for paper making could be solved if the Forest Administration were to 

 take the matter up seriously. 



Transport. — This is a more difficult problem to solve than the pre- 

 ceding one. In practice the freight from Sweden to Spain, to Pasajes (Gui- 

 puzcoa province) is lower than the cost of transport from Sierra Guada- 

 rama (province of Madrid and Segovia) to Guipzcoa or Biscay, where 

 important Spanish paper factories are situated. The Government may 

 prevail upon the railway companies to concede a lower tariff, but it can- 

 not improvise means of road transport. 



The Spanish paper industry has a producing capacity great enough 

 to meet the needs of the country ; the .Spanish Papermaking Company 

 is responsible for 68 per cent of the total output. Apparently means are 

 available to produce the whole of the mechanical pulp necessary, but 

 not the chemical pulp, because the manufacturers are not provided with 

 the needful plant. The paper factory at Villalba (Navarra) is an excep- 

 tion to this, as it produces a small quantity of semi-chemical pulp. 



Replanting with poplars, especially Canada poplar, is suggested as 

 a means of providing the most rapid solution of the problem, while at the 

 same time it would give a return of 12 to 14 per cent on the capital outlay.
