THERE is still a good deal for hard wood lumbermen to learn about drying different spec:es of lumber. Consumers find more or less fault continually with the present methods, or rather with some of them. It is dawning upon their minds that lumber of all kinds can be dried thoroughly and without injuring it in strength or texture ; that theie is no need of case hardening it on the outside while leaving the sap inside to sour and fer- ment and ultimately work its way to the surface to dis- color and ruin fine finish or to destroy the strength of the inteiior fibers by fungoid growths like dry rot, and that it need not be scorched and barbonized till the life is almost out ot it and the cohesion of its fibre destroyed. The art of artificially drying lumber is rising into the domain of science, and lumbermen are learning that not every dunderhead who has blundered on to the fact that heat increases the absorbing power of air, can build a suc- cessful dry-kiln. Millions of feet of hard wood lumber are annually ruined for fine use by improper artificial sea- soning, while the men who do the drying are totally ob- livious of the fact and the consumers do not know what is the matter with it. They realize that something pre- vents it fron taking the finish it should and that they cannot use it; but they do not know why. This subject needs continual agitating until it is better understood all around.—Hardwood. "Can any little boy here," asked the visitor, "give me an example of the expansion of substances by heat?''
