(From a drawing in theU. S. National Museum.) A triangular wood stringer capped with iron was used on the GreatWestern Railway when that road was relaid in 1857. The rail washeld in place by bolts as shown in Fig. 68, made from a drawing in the *Colburn & Holly, p. 92. DEVELOPMENT OF THE AMERICAN RAIL AND TRACK. 683 collection.

Previous to 1850 English rails were usually rolled in lengths of 15,10,and 18 feet; by 1855 the latter length became the universal standard. As improved methods were adopted in iron manufacture, the lengthwas increased in order to reduce the number of joints.* By 1857 railswere made at progressive mills 21 to 24 and 27 feet long and by 1860-65the 30-foot limit wa
