Imagine a strip of carpet across the United States at its widest part, the Forty-second latitude--a strip of “Hartford Saxony”, say, stretching from the Atlantic seaboard to the Pacific coast; and then another carpet strip the length of the United States, where this country is the longest--i. e., from the Northern boundary of the state of Minnesota to the Southern boundary of the state of Texas; then imagine one more strip stretching from Chicago to New Orleans, and finally a connection between the two latter strips at about the vicinity of St. Louis. With a mental picture of this vast country thus stripped with carpet, you wonder if there is that much carpet in the world. It seems incredible that this great sweep of land could be measured with carpet--and yet enough material comes every year from the looms of one carpet factory alone in this country to strip the United States East and West, and North and South as indicated above.] The weave is now completed; the rug comes out. But it is rough and has to be finished. It is passed through a machine that removes the roughness of the face as a lawn-mower cuts away the top-grass. The ends are finished, and the carpet is complete. ~SOME DESIGNS STAMPED ON YARN BEFORE WEAVING~ The pattern of tapestry carpet is obtained by printing the colors to appear in the design on the yarn which forms the face before the weaving is started, by means of large drums. After all rugs leave the weave-shop a force of skilled women examine them carefully to make sure that there are no defects. Every yard of the annual output of carpet and rugs is inspected five times before it leaves the factory. [Illustration: EXAMINING AND REPAIRING] [Illustration: PACKING FOR SHIPMENT] Why Do I Yawn? When you yawn, you do so because you have not been breathing quite properly and for some reason or other your blood supply has not been getting sufficient oxygen through the air which has been taken into your lungs. Nature’s way, in this instance, is to call for a big intake of air all at one time, and since it is important at such times that a large quantity of air should be supplied to the lungs at once, nature has so arranged matters that certain muscles shall cause you to open your mouth wide and take in as much air as you can at one time, and also has arranged so that it is almost impossible to keep from yawning when the demand for it is once made. The yawn is controlled by a part of our nerve structure which looks after the breathing apparatus. The satisfaction we feel after a wholesome yawn is due to the fact that having replied to nature’s demand that we bring in more air, our blood secures the oxygen which it needs and we feel the effect of better blood in our arteries at once.
