knitting for the trenches

I was poking around on google today trying to figure out how to do this one knitting thing, when I came across this - a 1917 New York Times article explaining what soldiers and sailors need in the way of knitted garments. It includes such useful advice as "If one does not know how to 'purl,' experts at Red Cross organizations and in the department stores, or experienced knitters anywhere, will be glad to explain the simple stitches." It sounds so useful, being asked to knit wool garments for the war effort.
