20 PEEMIUMS OFFERED BY THE SOCIETY IN 1868. 



5. CORSICAN FIR. 



For an approved Keport on the value, for economical purposes, 

 of the Corsican Fir, and on its adaptation to different soils and 

 situations — The Medium Gold Medal, or Five Sovereigns. 



The reporter's observations must go beyond the limited knowledge of 

 this tree as hitherto grown in Britain, and must embrace its nature, 

 uses, and adaptations in those countries of which it is a native. 



Eeports to be lodged by 1st November in any year. 



6. AMERICAN AND CANADIAN TREES. 



For an approved Report on the American and Canadian forest 

 trees adapted for cultivation in Great Britain — The Medium 

 Gold Medal, or Five Sovereigns. 



The reporter will enumerate and describe the varieties which have 

 been, or which may be, usefully introduced from North America — 

 the soils, situations, and conditions most suitable for them — their 

 economic uses and qualities, and the success which may have at- 

 tended the cultivation of any of them in Great Britain. 



Eeports to be lodged by 1st November 1867. 



7. FOREST TREES OF RECENT INTRODUCTION. 



For an approved Report on the more extended introduction of 

 hardy, useful, or ornamental trees, which have not hitherto been 

 generally cultivated in Scotland — The Medium Gold Medal, or 

 Five Sovereigns. 



The report should specify as distinctly as possible the kind of trees 

 introduced. The adaptation of the trees for use or ornament, and 

 their comparative progress, should be mentioned. Attention is 

 directed to the introduction of any tree as a nurse in young planta- 

 tions, which by growing rapidly for several years, and attaining 

 maturity when at the height of 20 or 25 feet, might realise the 

 advantages and avoid the evils of thick planting. 



Eeports to be lodged by 1st November in any year. 



8. ROOTS OF CONIFERS. 



For an approved Report of experiments on the uses to which 

 the fibrous parts of the roots of Coniferous trees may be applied 

 — The Medium Gold Medal, or Five Sovereigns. 



In North-West America, the fibrous parts of the roots of some Coni- 

 ferous trees are extensively employed for purposes similar to those to 

 which willows are applied in this country, more particularly when 

 the wood has been grown on soft, peaty soils. The object of the 

 premium is to elicit information regarding the possibdity of profit- 

 ably extracting and economically applying the vast quantities of 

 roots left in the ground. 



Eeports to be lodged by 1st November in any year.
