this have had the effect of reducing the cost from ^3, 3s. 4d. in 

 1 910 to j£,2 per acre in 1913, not including price of plants. 

 The species of trees which do most successfully on this land 

 are Sitka spruce, Norway spruce, and Scots pine. The best 

 species for peat of first class quality are Sitka and Norway spruce, 

 while Scots pine and Mountain pine grow well also. But owing 

 to their deeper root-system it is not advisable to plant the pines, 

 because much more money would have to be spent on deepening 

 drains during the first few years. The best species for peat of 

 second class quality are Sitka spruce, Norway spruce, and 

 Engelmann's spruce. 



The species that accommodate themselves best on peat of 

 third class quality are Scots pine and Mountain pine, while Sitka 

 spruce and Norway spruce, Picea alba, Picea Omorika, and Picea 

 E)igelman7iii will not grow on it even with the aid of artificial 

 manure. 



The best size of plants to use are 2-year i-year, although 2-year 

 seedlings of Scots pine also do quite well. 2-year 2-year spruce 

 do quite as well as 2-year i-year, but with the former more 

 difficulty is caused by the larger roots which are more trouble- 

 some to plant properly. The best season for planting all these 

 species is from March to May. 



8. A Plan Adequate to Meet our Needs for 

 Wood Timber. 



An important address on the above subject was delivered by 

 Dr B. E. Fernow to the Society for the Protection of New 

 Hampshire Forests, on the 23rd July 1913. 



A full report appears in the August issue oi Aitierican Forestry, 

 and the following excellent synopsis is given in the Catiadian 

 Forestry Journal of October last : — 



Dr Fernow began by stating that there was probably now 

 nobody who had not grasped the idea that the fundamental 

 object of forestry was to reproduce the forest crop which we had 

 used and, if possible, in better form. Looking over the United 

 States there was little attempt at reproduction. The population 

 was still growing, and, while a reduction in consumption, from 

 the present 250 cub. feet per capita per year to something like
