"Why are the2,better doors?

ttT i' ' I usr exacdy u,hir, ; .l Moore, are Lam- inex doors better than any other good doors?" "Big t &r Chief" Dicksonl I manager of the City j pa atHarcy Moore, the ' I salesman who was t tryngto tnterest him in stocking Laminex doors.

"That's a fair solidlrnbasillsDtitandchuk. question, Mr. Dick_ son, and I will answer it squarely," said Moore "You've had trouble with doors being returned because they warped-every lumber merchant has! Well, here is the answer!"

Moore noticed a rLxrz post that supported the second floor of the warehouse. It gave him an idea. "There is a solid post," he pointed out, "that is badly checked.^ Conseqriently, it is weakened. Drying out and taking moisture again have set up stresses in that post which hive finally caus6d it to split and check.

Now, there is one sur-e method of getting away from such stresses. The bridge builder has'used it for years-because a biidge will not bear up with checked timbers. The method is laninaiion. A great word. Please remember it. Thc bridge builder makes up his timbers of t%o or zo planks bolted firmly together. That is, he uses laminated construction because it is stronger and eliminates the internal stresses which cause checking and weakening of solid timber. That's lanzination'."

Harcy was off to a flying start.

"Now, with doors it's the same," he continued. "A solid stile develops internal stresses, too! The smaller the picice of wood, the less the internal stress to check and split it. But, if the changes of moisture were very gre t and rapid, such as alternately soaking in water and drying out rapidly at a high temperature, the solid stile would check and split. Nothing could prevent it.

"Now, the effect of the stress is to pull the piece of lumber out of shape, before checks develop. In other words, even a little moisture will warp the solid lumber. A door made of solid lumber will warp and twist out of shape to some degree with ^any change of moistur-e; it will swell some when it is in a merely damp moisture.' Here is the effect: The door does^not close tightly and will not fit snugly. But to fit well is just what the truly good door should do; and this the Laminex door uill dot"

Mr. Dickson still smiled, but with less doubt. "Well," he declared, "any stock softwood door doesn't fit closely like a hardwood door. "

"There you hit the bull's-€Ie," Moore replied, now thoroughly warmed up to his subiect. "Laminex does fit snugly, however. I'll develop your good point in proving it. First, do vou ever see anv modern hardwood doors built from solid lumber?"

"No, I don't think I have," Mr. Dickson agreed. "Go on, please."

"Now, here's the point," said Moore . " Laminex stlles and rails are built up of many pieces of wood, the bridge builder's rirethod of lanin- ation. The stiles are mhde up of a series of short blocksof wood, dovetailed and glued to two edge strips.

" Any stress that develops in any one blockoredgeisslight, because the piece is small. As.ain the dight stress"that may develop in any one piece will be counteracted by a stress in a piece having an opiosite pull bTcaase the
