7. AMERICAN AND CANADIAN TREES. 



For an approved Report on the American and Canadian forest 

 trees adapted for cultivation in Great Britain — The Medium 

 < lold Medal, or Five Sovereigns. 



The Eeporter 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 quahties, and the success which may 

 have attended the cultivation of any of them in Great Britain. 



Reports to be lodged by 1st November, 1866. 



8. FOREST TREES OF RECENT INTRODUCTION. 



For an approved Eeport 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 orna- 

 ment, and their comparative progress, should be mentioned. 

 Attention is directed to the introduction of any tree as a nurse in 

 young plantations, which, by growing rapidly for several years, 

 and attaining maturity when at the height of 20 or 25 feet, 

 might reabse the advantages and avoid the evils of thick plant- 

 ing. 



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



9. ROOTS OF CONIFERS. 



For an approved Eeport 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 

 Coniferous trees are extensively employed for purposes similar 

 to those to which willows are applied in this country, more par- 

 ticularly when the wood has been grown on soft, peaty soils. 

 The object of the premium is to elicit information regarding the 

 possibility of profitably extracting and economically applying 

 the vast quantities of roots left in the ground. 



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

 10. LARCH FORESTS. 



For an approved Eeport on the formation, progress, present 

 condition, and prospects of extensive Larch Forests in Scotland
