$8,000, making a total of $35,000.

The ratio of the three systems stands: Electricity, 1; cable, 1.09;
horse, 1.45.

4th. Construction of tramway.

Figures upon this point must necessarily be either averages or
approximations. The nature of the locality socially, naturally, and we
grieve to say it, politically, has a strong influence upon its
construction. Estimating on single track only, a horse road would cost
as an average $9,000 per mile. With electricity we have several
methods we can avail ourselves of: Surface, costing about $10,000;
overhead double conductor, $15.696; underground, $23,500.

With cable but one method, the underground, is possible. This cost is
variously estimated at from $30,000 to $110,000 per mile; however, the
latter figure is excessive. A fair average would be $35,000.

The ratio of constructions could be fairly placed as follows, putting
electricity as 1, by taking the average of the three methods at
$16,732: Horse road, 0.53; cable, 2.09.

Unquestionably a great majority of roads of the past have not been
constructions of engineering, and of all places requiring care, skill,
and engineering, the street roads are the places.

5th. Cost of operation.

A fair figure for cost of one horse for one year is $220.
