When the rails are slippery, great care is required to prevent the engine from slipping, by closing the regulator in time.
When about to enter a tunnel, the sand valves should be opened, and the sand allowed to flow freely until the train emerges from the tunnel—sand is cheaper than steam.
Never forget that lives and property depend upon the faithful performance of your work.

HOW TO BUILD A MODEL LOCOMOTIVE.
As a preparatory step toward becoming an engineer, it is highly desirable for the boy who looks forward to that honorable calling to familiarize himself with the different parts of the locomotive engine. This we have stated before.
There is no better way to accomplish it than to build a model locomotive.
At first glance this may seem to be among the things impossible, but it is not so, providing the boy has a mechanical turn, and any boy who has not better not think of becoming an engineer.
We now propose to give simple and accurate directions for building a model locomotive, accompanying the same with a series of illustrations, which we trust will be sufficient for the purpose intended.
