ort. The steel tubular bridge
Dr. Warneford had made for him, and it will bear the weight of a boy.
All the castings for the wheels and machinery of the engine and cars are
perfect in their way.

The readers of the ROUND TABLE will remember that last fall we published
a photograph of the perfect model of a trolley-car which not only ran by
electricity, just as an ordinary car does, but had all the details, even
to advertisements, that the trolley has. This trolley-car was an
extraordinary piece of work; but whereas the Warneford engine is not
more than eight inches long, the trolley was between two and three feet
long. The care taken in constructing the English train, engine, and road
must have been infinitely greater and the difficulties considerably
increased on account of its smaller size; but such work is not
impossible for any one with a mechanical turn of mind.

This whole railway, in fact, is a most interesting and suggestive piece
of work, and illustrates what mechanical ability and ingenuity can do,
and how much amusement and profit even so busy a man as an English
clergyman may find in working on such a thing as a hobby.

SOME DONT'S FOR SWIMMERS.

BY WILLIAM HEMMINGWAY.

It is just as dangerous to play with water as it is to play with fire.
Probably no sport is more dangerous than swimming, just as none other is
quite so delightful. If you use proper caution no exercise is safer than
swimming.

But what is proper caution? It is almost impossible to learn how to swim
by reading any amount of printed instructions, but it is easy to learn
how to take care of one's self in the water. One of the best swimming
teachers I ever knew summed it all up in these words: Don't be rash.
Don't be frightened. It seems to me that no advice can be better than
that. I think that one more rule is safe to follow, Don't "show off."

Let us look at what happens to the rash swimmer and diver. Probably
every one of you has known or heard of some poor over-confident fellow
who has lost his life by diving overboard without knowing the depth into
which he was plunging. Nothing can be more dangerous. There is a fine
swimming-beach at the upper part of the Harlem River, near Farmers'
Bridge, on the Manhattan Island shore. There are bath-houses in plenty,
and a long stretch of firm sandy shore. One of the best oarsmen of his
year went swimming there a few years ago. He had just come to the end of
five months' hard training a
