BY GEORGE W. MANSFIELD.

Why should we prefer electricity as the propelling agent of our street

cars over all other known methods? I answer, without hesitation,

because it is the best, and being the best is the cheapest. Briefly I

will present the grounds upon which I take my stand.

To-day the only methods for tramway service are three in number:

Horses, with a history of fifty years and over; cables, with a history

of fifteen years; and electricity, with a history of two years. I give

the latter two years on the basis of the oldest electric street

railroad in existence to-day, and that is the Baltimore railroad,

equipped with the Daft system.

The main points for consideration common to each are six in number:

1st. Obtaining of franchise.

2d. Construction of buildings, viz., engine house or stable.

3d. Equipment--rolling stock, horses, engines and dynamos.

4th. Construction of tramway.

5th. Cost of operation.

6th. Individual characteristics and advantages.

Each of these requires a paper by itself, but in as concise a way as

possible, presenting only the salient reasons and figures, I shall

endeavor to embody it in one.

1st. Obtaining of franchise.
