No better opportunity is afforded for a saving than by pur-chasing railway timber and ties under careful specificationsand adequate inspection. There is a very great variation inwood, and the life of our present market lumber is short atthe best. Several steam railroad companies in this countryare now employing experts on timber and allowing themto operate along a very broad gage plan.

All the standards shown arestraight 100-ft. radii. Many advocate spiral switches, but itdoes not seem that there is much to be gained by further ease-ment when one takes into consideration the limited space,short center radii and slow speed with which an engineer gen-erally contends in city service. If in double-track work the de-sign calls for clearances at curves, a greater variety of switchesand mates is required. It is a question whether it pays to reconstruction the writer had charge during last summer. It isnot his intention to discuss the merits of timber preservationin this article, but it seems that such examples as the one illus-trated are quite sufficient to show that we should not hesitateto invest something in a reliable timber treatment to savereconstruction.
