drought better than the European variety, but in this he is 

 shown to be wrong by the results of the past year. It is an 

 important point. He prefers Abies concolor to A. pecthiaia, 

 since the latter requires much rain, but there do not seem to 

 be sufficient data yet about the concolor to justify him in 

 adopting it. Indeed the introduction of silver fir at all in such 

 conditions as M. Jolyet is considering seems very doubtful. 



M. Jolyet's proportions at the start are as follows : — Out of 

 4350 plants to the hectare (or 1740 to the acre), planted about 

 5 feet by 5 feet, the spruce to number 1905, the Scots pine 1360, 

 the larch 270, the Douglas 545, A. concolor 135, and beech and 

 sycamore (half-and-half) 135. 



Beginning the thinnings with the spruce and Scots pine the 

 progress of the plantation is to lead at 60 years to a standing 

 crop on each hectare of 865 spruce, 320 pines, 135 larch, 270 

 Douglas, 135 firs, and 135 deciduous trees.

 half-yearly issues of the l^ransactions. But as the response 

 has not come up to his expectations, he ventures now to 

 renew his request for literary contributions. If proprietors, 

 factors and foresters would contribute to our pages from 

 the vast store of practical knowledge they have acquired, our 

 publication would at once assume a highly increased value 

 and interest. We have given our readers, from time to time, 

 articles by the highest authorities on general questions of policy 

 and practice ; and of such articles a sufficiency will, without 

 doubt, continue to become available. But of communications 

 regarding the application of acknowledged principles under the 

 conditions here prevailing we have hitherto seen far too little. 

 Owners and their professional assistants come and go, without 

 leaving behind them, for the guidance of their successors, any 

 trace of the invaluable experience they have accumulated. 

 If they would, from time to time, give us the benefit of this 

 experience, pointing out by what means, and with what measure
