Show A NEW BUILDING MATERIAL to the mining camp in its incipiency tile the subject of lumber for building purposes is an all important question while to the camp established lumber buildings become a source of menace where fire protection is extremely limited and brick stone or concrete are demanded for permanent construction st thus the item of building material becomes a problematical factor and a serious one to build of lumber has of necessity been the primitive inclination in all western camps and to dispense with wooden buildings the eternal desire after the town had grown to an extent that permanency was the promise A building material equal to and under lumber in cost and having the efficiency of brick has been realized in the gypsum blocks now being manufactured in utah and california under the patents of J D sullivan of salt lake mr sullivan has worked out a system whereby the enormous gypsite beds that are known to a half a dozen western states may be utilized to supercede supersede super cede brick stone and cement in the building of fireproof structures on a large or small scale the original purpose of the sullivan wall was for interior partitions in large buildings to do away with the necessity of lathing and studding making a lighter stronger and smoother wall as well as possessing the requisite fire repellent properties the installation stal lation for that purpose was immediately successful and the course of manufacture with various experiments developed a block that would serve with like efficiency for outside construction being practically the same materials as used for the inter interiors lors but in wider dimensions to give added strength for the building of cottages such as the average mining camp demands the sullivan wall is said to be especially adaptable and with the unlimited deposits of the basic material required in the very hearts of oe many of the mineralized districts it would seem that mr sullivan has mastered tho the question that has been a serious drawback to the up building of mining towns in a substantial manner like many another important discovery the manner of handling the sullivan is extremely simple the blocks being twelve inches high and thirty two inches in length and are laid in the same manner as brick only that in place of mortar the same composition of which they are made is used to bind them together making the complete wall equivalent to one solid cast requiring merely a thin inside coat of plaster and a pebble dash or other water resistant finish on the outside being a hollow block and I 1 laid a id in uniformity so that a continuous air space as well as a continuous solid at intervals of sixteen inches is attained making a structure by heat or cold and consequently warm in winter and cool in summer |
