The cost of planting one acre with 400 banana trees varies from £ 10 

 to £ 14 IDS. according to the price of the plants, which ranges from £ i 12s to 

 £ 2 85 per hundred. Land suitable for banana growing costs from £ 29 

 to £ 54 per acre, and plantations in full bearing are valued at about 

 £ 96 per acre.

 Year 33, No. 35, pp. 199. ^lontpellier, August 27, 1916. 



During the prolonged drought of the summer of 191 6 in the South 

 of France some measurements were made of the sizes of grapes.

Being given that volumes are to one another as the radii raised to the 

 third power the ratio 1549.29 : 636.05 is obtained ; in other words, the 

 berries which have suffered from drought are nearly three times as small 

 as normal grapes. 



iiSS - Spanish Forests and Paper Manufacture. — Elorrieta o. in Rcsumen de Agricui- 



tufa. Year XXVIII, Part 9, pp. 399-402. Barcelona, September 1916. 



The Spanish market uses annually 28 000 tons of paper, of which 

 newspapers account for one half. Spain produces 15 000 tons of mechan- 

 ical pulp per annum, from which an approximately equal weight of pa- 

 per is manufactured. Consequently she is obliged to import 3 000 to 4 000 

 tons of mechanical pulp and 10 000 tons of chemical pulp. 



Trackless forests. — It is a.sserted that there is sufficient wood in 

 vSpain to cover the amount of the imports and that it is the lack of roads 

 which hinders the working of the woods under economic conditions. In 

 Spain the raw material for paper making is not very costly, but no-one 

 cares about it and the forests remain practically unusv^d. As an instance 

 may be cited the magnificent fir woods of the Aran valley consisting of 

 Abies pedinata, the species best adapted to paper making. A beginning 

 was made in the management of 37 500 acres, and the yield from these 

 forests reached nearly 16 000 cubic yards. Unfortunately the work was 

 stopped on account of administrative difficulties connected with bounda- 

 ries and other questions of secondary importance. 



Workable woods. — In the Pyrenees of Aragon and Catalonia, chiefly 

 in the provinces of Huesca and Lerida, there are 122 500 acres of firwoods 

 capable of providing 39 000 cubic yards of wood per annum. As the wood
