Increasing efficiency and decreasing cost in school house construction with keystone gypsum blocks. hen its cost is pro-hibitive, the building can be made slow-burning, andpractically fireproof, by the use of KEYSTONEGYPSUM BLOCK PARTITIONS. The extremelightness of these blocks permit their use on woodfloors without overloading, and while their cost, aftertaking the saving in plastering into consideration, isabout 15% greater than wood stud partitions, this is inmost cases more than offset by the economy in the useof KEYSTONE FLUE BLOCKS.

There are three questions that must be conclus-ivelv answered regarding any partition material as aprecedent to its consideration for school house con-struction, viz: Is it fireproof in every sense that the word implies ? Is it sound-proof? Does it form a rigid partition P All three of these points are of equal importance. The following pages not only offer convincinganswers to each ot these questions, but demonstratethe additional advantages of economy and lightness tobe secured by the use of KEYSTONE GYPSUMBLOCKS. s? 3 cro o o 3 m< o co Wo o 3.
