240 ON THE MACKINTOSH ESTATE IN BRAE LOCHABER. 



clays hang down in a withered condition. The two insects do 

 not attack the same tree, or the result would be very destructive 

 to the plantations. 



Judging from the size and healthy condition of the old larches 

 and from the rapid growth of the young plantations, it is evident 

 that larches thrive best on soils of alluvial formation similar to 

 that found in the terraces referred to. It is also clear that the 

 mild and moist nature of the climate is favourable to the healthy 

 development of the plantations. I am also of opinion that the 

 larches grown on such soils are more free from disease than those 

 on grounds having a light surface and hard subsoil which in my 

 judgment is the origin of most of the diseases to which the larch 

 is subject, especially those that affect the roots.
