also displayed, showing the advantages of deferred thinning 

 in the culture of common spruce. 



Mr R. M. Macdonald of Largie sends two boards of Cupressus 

 macrocarpa showing very fast growth, the tree giving a girth 

 of 7 1 feet at the age of 35 years. 



In the section for " Gates, Fencing Material, Railway 

 Timber, etc.," we have from Murthly a Douglas fir sleeper (not 

 creosoted) used on the Highland Railway for about seven years, 

 showing splendid wearing qualities ; also two posts of Douglas 

 fir (not creosoted) in use for fourteen years in dry gravelly soil, 

 and still in perfect condition. Scone is well to the front in this 

 class, showing a very fine five-barred gate and wicket, made 

 from larch of really superb quality. The design here is very 

 pleasing, and the mechanical arrangements for hanging and 

 fastening very effective. A split-oak hunting wicket, made on 

 the self-closing principle, is also exhibited, and is a useful 

 article for a hunting country. A good representative set of 

 creosoted fencing posts, cut from a variety of timbers, is also 

 sent. Each specimen is cut and hinged, thus showing the 

 extent of the absorption, and the difference in regard to this 

 in the case of seasoned and unseasoned posts. 



From Floors Castle comes one of the Scots pine gate sets 

 used on the estate ; also an interesting stand of fencing posts 

 of various sizes, cut from sap-wood and heart-wood of Scots 

 fir. These have been all treated in the estate creosoting plant 

 at a pressure of 150 lbs. Each specimen was weighed before 

 and after seasoning, also after treatment, and the results are 

 neatly tabulated, so that the whole form a most interesting and 

 instructive exhibit. Six posts which have been in use for 

 eight years are also shown. These are perfectly preserved, and 

 prove the economic advantages of using creosoted Scots pine 

 for fencing purposes, and thus saving more valuable timber 

 for the market. 



From Novar we have three field-gates made of larch and 

 treated with sideroleum. They are of light, medium, and 

 heavy pattern, and are good serviceable articles for general 

 field-work. Creosoted hand specimens of Scots pine straining 

 and fencing posts, of Douglas fir fencing posts, showing the 

 extent of absorption, are also shown. 



The Economic Fencing Co., Ltd., London, sent a quantity 

 of their well-known " Peignon " chestnut fencing, sufficient
