This booklet describes and analyses the demanding situations and possibilities of amenity migration to mountain components and its administration, and provides similar ideas. The book's chapters conceal the topic via case experiences at foreign, neighborhood and native degrees, besides overarching issues comparable to environmental sustainability and fairness, mountain sport clients, housing, and non secular motivation.

Recom­ m e n d e d working stresses contain a factor of safety to provide for the effects of temperature ranges in ordinary construc­ tion, and usually no further consideration of temperature is necessary. Tests of wood conducted at about —30()°F show that the important strength properties of dry wood in bending and in compression, including stiffness and shock resistance, are much better at extremely low temperatures than at normal temperatures. Exposure to high temperatures, on the other hand, can weaken wood in two ways.

Sanding of surfaces should be limited to special circumstances, mainly for some species of hardwoods. ADHESIVES T h e structural adhesives used in Britain fall into three main groups being Phenol Resorcinal, Casein, and Urea. Phenol Resorcinal glue possesses all the qualities most desirable in a structural adhesive, including water resistance. It is, as one would expect, an expensive glue and more difficult to apply, requiring strict observance of heat treatment and timber conditioning, but resulting in the best quality glue line and, therefore, product.
