termed pure larch, although four or five other plantations were 

 sparsely mixed with deciduous trees. 



" Amongst the various trees included in the plantations we found 

 that the deciduous were represented by oak, ash, beech, sycamore, 

 wych-elm, sweet-chestnut, and a few birch here and there. The 

 conifers were chiefly larch, Scots pine, spruce, Douglas fir, Corsican 

 pine, Austrian pine, and a few other varieties in small quantities. 



"The average cost of planting amounts to about 7 per acre 

 estimating the value of the trees at 2os. per 1000 and that of ma- 

 nagement and thinning to 2os. about per acre. 



" The most serious pest we found traces of was the Argyresthia 

 loevigalella. In addition to this we found examples of the larch- 

 miner (Coleophora laricella\ and larch-aphis (Chermes larici). 



"The only serious fungus was the larch blister (Peziza Will- 

 kommii \Dasyscypha calycina}) although the high altitudes and the 

 generally dry soil were not favourable to its growth."

This exhibition was undoubtedly the most important forestry col- 

 lection ever seen in England. 



Great credit is due to the cooperation of the R. English Arbo- 

 ricultural Society in the organisation of this splendid show which 

 comprised no less than 248 separate entries and illustrated admi- 

 rably the whole field of sylviculture, utilisation of timber and forest 

 protection. 



For the first time a gold medal was offered for the best general 

 collection of exhibits in the Forestry section. 



Among many interesting things to be seen there were three 

 exhibits illustrating the different rates of growth and varying qua- 

 lities of the wood of Scots Pine, grown under varied conditions 

 of soil and of climate.
