Show proper amount of water to which the oil is added, and the whole mixed until all trace of the oil has disappeared. Whenever you begin to think that a page or one-half a page advertisement each week in your local paper is expensive, just remember that one of the big mail order houses spend $12,000, 000 every year for its catalogue. They are after the trade which belong to your town, and believe in printers ink to get it. What are you doing to counteract them ? Mr. Merchant, just store this thought under your hat: Every country town that has a newspaper news-paper it missing a harvest if its merchants do not make it a mail order catalogue. Every inch of its advertising space should be used. Don't be afraid to advertise adver-tise your prices. That is ' the whole secret of successful merchandising. mer-chandising. Price, first, last, and all the time should be the big feature. Your name in big let-trs let-trs will not pull trade. Prices and plain figures will do so. Among other things which the U. S. is to profit by on account of the great war in Europe,, is the raising of sugar beet seed. Agricultural colleges of various states are experimenting on seed raising and preparing to raise them continually. Impervious Cement Gov. Experiments Produce Pro-duce Good Results The U. S. Government has been employed for some time in making extensive tests for the purpose of fixing definitely the value of an oil mixed concrete for damp cement construction-The construction-The tests have resulted in the following conclusions: That the admixture of certain mineral oils in small proportions, not to exceed ex-ceed 10 of cement used, does not lessen the the tensile strength of mortar, that concrete con-crete mixed with oil takes much longer to set hard, perhaps twice as long; that the use of oil does not make the concrete impervious imper-vious to watr under heavy pressure, pres-sure, but does make it practicaly non-absorbent under low heads. The value of oil mixed concrete it is said to be particularly great in the construction of basement floors, walls, watering troughs, and all parts of concrete structures struct-ures that are to be damp proof. Many walls now in existence may be improved by the application applica-tion of an oil mixed mortar coat to the old surface. A mortar of 1 part cement, two. parts sand, and containing 5'r oil should be sufficiently non-absorbent for this purpose. Attention is called, however to the fact that extreme care in the proportioning, mixing and placing plac-ing is absolutely necessary if the waterproofing agent is to be of any value, Particular care should be taken to insure that the oil 13 thoroughly mixed with the other materials, and the time of mixing should be about double that when the oil is not used. The kind of oil is also important. import-ant. The oil should be a fluid petroleum product, and should contain no admixtures of fatty or vegetable oils, must have a certain specific gravity, must stand certain tests when heated, and must be able to show no emulsification when shaken up with a certain per cent of caustic soda. These tests are given fully ful-ly in Bulletin No. 530 of the the Dept., entitled, Oil mixed Portland Cement Concrete. The oil should in no case exceed 10 of the weight of concrete, and in most cases, 5 is all that i3 necessary. Since a bag of cement weighs about 94 lbs., about 2 qnarts of oil should be added for each bag of cememt used. The sand and cement should be first mixed with the |
