TRANSPLANTING OF TREES. 



more sensitive to cold, than that of trees exposed to 

 all weathers, and their roots are much fewer, and have 

 a slighter hold of the ground. It is evident, therefore, 

 that the trees left standing in over-thinned plantations, 

 being ill-prepared for their new circumstances, are 

 sure to receive a severe check ; which, if it does not 

 kill them outright, will retard their growth for many 

 years, or stunt them to an extent from which they may 

 never recover. 



The thinning of fir plantations need not begin be- 

 fore the trees press so much on each other as not only 

 to check the growth of the lower branches, but also 

 to kill a portion of those next the ground. 



In hardwood plantations, the thinning commences 

 when the nurses press so much on the permanent trees 

 as really to injure them ; but only such trees should 

 be removed as actually do so. When the pressure is 

 slight, it may be relieved by cutting back the nurses 

 to half their length, and they may be allowed to re- 

 main till the advance of the hardwood requires their 

 entire removal. From the time that all the nurses 

 are removed, in each of the subsequent thinnings 

 which are necessary to leave the permanent trees that 

 are suitable for the formation of large timber, those 

 trees should first be cut down which appear to press 

 on their stronger and more healthy neighbors, and to 

 deprive them of the room and nourishment needful to 

 their increasing growth. 



Transplanting of Trees. — In the improvement of 

 the park and pleasure-grounds, much may be effected 

 by the transplantation of trees of a considerable size. 

 "Where suitable trees are to be had, they may often be 

 effectively employed in the formation of groups in the
