Has a Rate of Speed Equal to Ninety Miles an Hour, ever Been Attained
by Railroad Locomotive?--It is extremely doubtful if any locomotive
ever made so high a speed. A mile in 48 seconds is the shortest time
we have heard of. A rate of 70 to 75 miles per hour has been made on
a spurt, on good straight track. The Grant Locomotive Works could make
such an engine. Sixty miles an hour for a train is considered a very
high rate of speed, and is seldom attained in practice for more than a
short run.
The Fastest Boat in the World.--Messrs. Thornycroft & Co., of
Chiswick, in making preliminary trials of a torpedo boat built by them
for the Spanish navy, have obtained a speed which is worthy of special
record. The boat is twin-screw, and the principal dimensions are:
Length 147 ft. 6 in., beam 14 ft. 6 in., by 4 ft. 9 in. draught. On a
trial at Lower Hope, on April 27, the remarkable mean speed of 26.11
knots was attained, being equal to a speed of 30.06 miles an hour,
which is the highest speed yet attained by any vessel afloat.
Staining and Polishing Mahogany.--Your best plan will be to scrape off
all the old polish, and well glass paper; then oil with linseed oil both
old and new parts. To stain the new pieces, get half an ounce of
bichromate of potash, and pour a pint of boiling water over it; when
cold bottle it. This, used with care, will stain the new or light parts
as dark as you please, if done as follows:--wipe off the oil clean, and
apply the solution with a piece of rag, held firmly in the hand, and
just moistened with the stain.
