data is based, frankly, upon European practice, but the modifica- 

 tions suggested for British India will be interesting to 

 silviculturists. T. S. W., Jr.

Emile Mer gives some interesting figures 



Thinnings on the yield in cubic metres of spruce 



and stands after thinning. His conclusions are 



Yield that, in the regular spruce stands of the 



Hautes-Vosges, the thinning should not only 



be begun early (25 years or thereabouts), but should be quite 



heavy, not only from the point of view of yield, but also for the 



sake of the production per cent. His conclusions are clear cut and 



decisive, notwithstanding a previously admitted theory that the 



young spruce stands should be kept dense.

V. Boutilly, Inspector of the French 



Rodent Waters and Forests Service at Algiers, 



Damage reports lack of success in reducing rodent 



damage by the use of "minium" or sulphate 



of copper in solution. 



Boutilly, who has charge of the forestation around Algiers, 

 found that the only method of reducing rodent damage was to 

 thoroughly brush out and clear the land to be sown instead of 

 being content simply to brush out seed spots or strips. With 

 complete clearing "the rodents have no clumps to hide in and 

 almost all leave the area, and the damage is reduced accord- 

 ingly. Moreover, I have noticed that the young cork oak plants 

 which are quite tender during youth . . . , especially at the 

 end of summer, resist the heat better if they are uncovered 

 than they do if they are growing in the midst of brush. I 

 think that this phenomenon is due to the freshness caused by 

 proper aeration."
