HASELMANN,

Manager of the Aix la Chapelle-Burtscheid Tramway.

Here are some unquestionable results. For nearly a year the first railway

engine, and for six months the first tramway engine of this new

construction, have been introduced into regular public service, and been

open to public inspection as well as to the criticism of the scientific

world. They are worked with greater ease and simplicity than ordinary

locomotive engines; the economy of their working appears, allowing for

shortcomings unavoidably attached to small establishments, to be at least

equally great: they do not emit either steam or smoke, and their action

is as noiseless as that of stationary engines.

In view of these facts it might be expected that railway managers, who

are continually told that the smoke of their engines is a serious

annoyance to the public, would be eager to make themselves acquainted

with them; it might, in particular, be expected that the managers of the

underground and suburban railways of this metropolis would lose no time

in making experiments on their own lines--if only by converting some of

their old engines into those of the fireless system--and assist a little

in the development of an invention, in the success of which they have a

tangible interest which is much greater than that of any railway on the

Continent, but there is no sign yet of their having done anything.--_E.,

in The Engineer_.
