plantations ; and to prevent its breeding, the dry stumps are 

 removed. These realise the cost of their removal, and in some 

 cases from is. to is. 6d. more per acre. Collecting the insects 

 does not answer, and it is found much better to grub the stools. 

 In one portion of this wood, which is just 80 years old, the 

 felling realised 40s. per acre for each year of its growth. 

 The small spruce is converted into pulp, and is sold in 

 three classes, at from 7s. to 8s. per cubic metre (35 '2 cubic 

 feet) for the lowest class, and up to 9s. for the highest class. 

 Two thinnings during fifty years amounted to 200 cubic feet, 

 and realised 28s. per acre. In 1898, 528,000 cubic feet 

 were blown down in this forest in two hours. Another 

 portion of the same forest visited was 95 years old, and was 

 estimated to contain about 9360 cubic feet per acre, but the 

 actual results generally work out at 5 per cent. more. The 

 nursery plants are left in the row until they are three years old. 

 Stock-maps are made every ten years. New plantations cost 

 from 46s. to 47s. per acre, and the average receipts over the 

 whole forest for the last five years were 42s. per acre. We saw 

 spruce here standing 108 feet high. Two hundred and fifty 

 acres are set apart, and a most careful note is kept in detail, 

 so as to give data for the whole forest. 



To me this forest was particularly interesting. It extends 

 over the same area as is covered by the Novar Woods, and 

 the plan of cutting so many acres annually is in accordance with 

 the plan in operation at Novar. One thing, however, that 

 accounts for the large revenue from such an exposed district 

 is that there is a duty on all imported timber, which gives the 

 forest a monopoly; and with the numerous mills already referred 

 to in its immediate vicinity, it commands an excellent market 

 for spruce for pulp-making. 



We visited the forest of Crottendorf on the 24th of June. 

 It also stands at a high elevation, the highest portion being 

 3000 feet. Consequently it is liable to a great deal of damage 

 from storms coming from the north. The trees on the eastern 

 slope are very much destroyed, and the felling-direction has 

 here to proceed from south to north. The severance-cuttings 

 are replanted. Great damage is experienced from game, and 

 a number of the trees which are broken by the wind have 

 previously been injured from this cause. One part of the wood 

 we visited was 70 years of age. Fourteen thousand cubic feet
