The bottom of switch tonguehas oblong and diamond shaped lugs, which slide on themetal cross bars D, and readily cause any dirt whichmay gather in the switch to drop into an iron box beneath,which may be connected with sewer where desired. Itis claimed this reduces the work of track cleaners, as alldirt is cut and easily made to drop into the box belowwhenever switch is turned. The whole may also be used.

Bytheir use it may confidently be expected that the life ofthe flues will be fully twice that steaming under the samecircumstances without them, not to mention the saving inexpense of washing.
