106 FORESTRY IN SJPAIN. 



tine, at 60 reals = 7680 reals ; 5 arrobas of breas, tar resulting 

 from the borras and impure resin, at 12 reals = 60 reals 

 in all, 12,877 reals. 



'The expenses were : 



420 days' wages of the men, two in number, employed in 



collecting the resin, at 14 reals, - - 5880 reals 



210 days' wages of a boy, assistant to them, - 1260 ,, 



10 per cent, interest on the capital of 15,000 reals invested 



in the small fabrique and utensils employed, - - 1500 ,, 



10 per cent, on the sum of these for unforeseen incidental 



expenses and the direction of the work, - 864 ,, 



9504 reals 



' Deducting the expenses from the returns, there is a 

 nett gain of 3373 reals, corresponding to a gain from each 

 tree of 67 reals. With the problem thus solved, showing 

 that it would be profitable and satisfactory to continue 

 the resination of stone pines, the proprietor did not hesitate 

 about submitting to this method of exploitation a greater 

 number of trees. 



'In the year following he subjected 75,000 trees to this 

 treatment, and judging from the quantity of turpentine 

 obtained during the first month of operation, it may be 

 supposed that the products, if not superior to those yielded 

 in the experiments of the previous year, would have been 

 approximately equal to them ; but the political movements 

 which were so accentuated in Cadiz arid the province 

 around, prevented the ascertaining in an indubitable 

 manner of the entire production, as during a third part of 

 the time of the resination the operations were stopped. 



' Let it be supposed, and it is no great concession, that 

 the 75,000 trees yielded proportionately the same profits 

 as were obtained from the exploitation of the former 5000, 

 there would result a nett return of 50,574 reals. 



' In the year 1874 the resination was extended to 120,000 

 trees, but the work has been stopped in consequence of 

 ruinous losses to which the proprietor of the state has been 

 subjected through operations of a different kind, and the 

 lamentable depression of trade which has come upon all 

 our larger towns.
