Thesecret of the success of brick paving for use with T rail,is the fact that it furnishes a smooth surface with closejoints, and the bricks can be moulded or chipped to anyshape so as to make a good fit, not only with the mainpart of the rail, but at the joints and fishplates. A greatmany companies are in the habit of making their own Trail curves, the guard rail being made of a lighter sectionof T rail placed on blocks or chairs. This is claimed tobe a cheap and durable construction, as the curves willwear as long as the head of the guard rail will last, whichis of course, a good while. In many instances the guardrail is put only on the inside. When the paving is down,these rails have the appearance of being one piece withthe track rail. HOLBERT SAND BOX.

It is claimed that it will pulverize almostanything short of solid rock,—wet sand, soft coal and. HOLBERT SAND BOX. building brick proving easy prey for it. The spiralmotion given by the fan shaped blades and auger shapedshaft is very persuasive in making the sand come down,no matter what shape it is in. Motion is given to thisshaft by a treadle operated with ratchet and recoil spring,as a glance at the drawings will show. ROPE DRIVING. William Kenyon, the English authority on rope driv-ing, says in an article in Lightning, that the velocity ofropes on a rope drive should be between 3,000 and4,600 feet per minute, though good results can beobtained with higher velocity. Horse-power can be cal-culated on a basis of lO-horse-power for 1,000 feet ofspeed with i^-inch diameter rope, and 5-horse-powerfor 114!-inch rope. The Unicycle Street Railway Company, of St. Louis,is pushing forward its one-wheeled scheme. (^^msdrJ^^AWijUfJ^^ 38 REMINISCENCES OF MR. RICHARDSON.
