322 ENGINEERING ON THE FARM 



is not merely painted on the surface. Linoleum is made of 

 a layer of burlap on which is pressed the desired thickness of 

 the compound. It wears out from beneath about as fast 

 as from above on account of water which finds its way to 

 the burlap underlay. It is essential, therefore, when lino- 

 leum is laid, that the edges be made tight and cemented 

 down, in order that no moisture may get under the surface. 

 The laying of linoleum requires considerable time. It 

 should first be unrolled on a flat surface and allowed to flat- 

 ten out. As it will creep for several days, it is impossible 

 to unroll and fit linoleum the same day. If this is attempted, 

 there will be shrinkages and bucklings. If a floor covering 

 of low cost is desired, where appearance and color of finish 

 are not an object, a heavy grade of rolled roofing may be 

 used. This should be treated the same as the linoleum with 

 reference to creeping and buckling.
