Wide-Wing Spring Posts for Right-of-WayFencing The tendency toward more durable right-of-wayfencing than is afforded by the ordinary wooden post orshort-lived metal post is indicated by the earth-cush-ioned spring-post system of the Carbo Steel Post Com-pany, Chicago, 111. The outstanding merits asserted forthis construction may be taken up in the followingorder: Easy Transportation and Installation—The posts aremade of rust-resisting steel of such high tensile strengththat a very light and properly designed section will takecare of strains that would upset other posts. It isnecessary only to drive the post to one-half the depthused for wooden posts, since the carbo post (anchor-drive type) is furnished with wide wings that give anexcellent anchorage. This post, furthermore, can beinstalled in cold INSTALLATION OF A CORNER POST 808 ELECTRIC RAILWAY JOURNAL [VOL. XLV, NO. 17 Springiness—When in a fence theposts act like a spring—the earth itselfbecomes the shock absorber of the cutting through the ground at theground line, the posts transfer the usualbreaking-off strains at that line to thefencing itself.

Sanitary—Wooden fencing posts arenow recognized as favorite haunts ofthe clinch bug and other farm this reason right-of-way fencingthrough farming country should be freefrom this source of trouble, even wherethe law does not forbid wooden posts.
