INVENTION AND DISCOVERY.

DETACHABLE SHELVING FOR WINDOWS.--The scent and the sight of flowers are

the source of so much enjoyment to most persons, and the means of

keeping them in our houses, as a rule, is such a puzzle, that the

"detachable shelving for windows" ought to find favor with everybody,

young or old.

This shelving is an apparently simple arrangement of three shelves

connected by strong braces running from one to another, and attached to

the sides of the window in two places by screw-eyes and nuts which are

securely fastened in the outer frame of the window. Simple as it

appears, it is very ingeniously contrived, and forms a most desirable

substitute for the window-ledge itself, which is seldom wide enough for

flower-pots to stand on with any degree of safety.

STATION-INDICATOR.--We remember once travelling in the winter in almost

the last car of a long train, where we could not see the names of the

stations; the conductor shouted out the stopping-places in a way not

easy to understand, and we had no time-table and did not know when the

train was due. It was the most uncomfortable journey it is possible to

imagine. A station-indicator in each car would forever prevent the

recurrence of such discomfort and anxiety. Curiously enough, two have

been invented within six months; the later one has an endless roll with

the names of all the stations on the route, and, by the movement of a

simple bar, after passing one station the name of the next one appears

in its place.
