For detailsthose who care to investigate may be referred to a pamphlet on the sub-ject, that can be obtained by addressing the Inventor at the above namedplace. At a glance, the problem of a street-railway differs from the steamroad in that the former is surrounded by the roadbed, while the latter isat least to a great extent, exposed. The effect of the surrounding roadbedis twofold. First—By its great surface friction, it tends to hold the rail againstchange, stops all wave motion, and Second—It to some extent modifies the temperature. The problem was to find a measure of value for both. To this end thefollowing experiment was made. One rail in a section of track was so c
