The Influence of Sunlight and Moonlight on Edge Tools.

It is not generally known that the light of the sun and the moon exercises a deleterious effect on edge tools. Knives, drills, scythes, andsiekles assume a blue color if they are exposed for some time to the light and heat of tho sun; the sharp edge disappears, and the tool is rendered absolutely useless until it is retempered. Purchasers should therefore be on their guard against buying tools from retail dealers and peddlers which, for show purposes, have probably been exposed for days together to tho glare of the sun. The unservicoableness of tools acquired under these conditions is generally wrongly attributed to bad mutcriul or to inferior workmanship. A similarly prejudicial effect has been exercised bymoonlight. An ordinary cross-cut saw is asserted to have been put out of shape in a single night by exposure to tho moon.—[lron.
