NOTICES OF AUTHORS. 



We have tried a number of kinds of abies, in both 

 dry and moist clay, and have found they did not 

 grow so luxuriantly (thrive so well) as Scots fir or 

 larch. The silver fir shewed superior adaptation to 

 any of the other kinds of abies. 



Almost in every instance where we have seen the 

 silver fir and Norway spruce (by far the best spruce 

 for Scotland) growing together, the former was the 

 superior. The timber, in the lower part of the stem, 

 is harder than that of the spruce, but freer and more 

 porous in the upper part. It is probable that the 

 silver fir will not thrive in so elevated or so moist a 

 situation as the spruce, but in all favourable soils it 

 merits a preference. 



We now come to a very important part of our 

 author's volume— an account of the most economi- 

 cal, and, as he says, the most STiccessful, mode of 

 planting moors and bleak exposed mountains, but 

 which is brought forward by him under no limita- 

 tion to place. To the invention of this method, our 

 author lays no claim ; he merely describes the prac- 

 tice in a clear and judicious manner. 



" The most proper time for removing firs from 

 the nursery to waste land, is when they are two 

 years old." — " The experience I have had enables 

 me to say, with as much confidence as I can speak on
