were still new. Before the transport reached Haiphong, war was declared; and, upon her arrival in Haiphong, the ship was loaded with a cargo that had become war contraband, the 75,000 guns having been sent with a good lot of ammunition. The matter was put into the hands of the English Governor, who had the guns and the ammunition put ashore and locked up. Korea will have to wait until the war is finished to obtain her guns."

Shipbuilding at New London, Conn.

IX THE YARDS of the Eastern Ship *■ Company, New London, Conn., two large steamships, the Minnesota and the Dakota, to run on the Pacific Ocean for the Great Northern Railway, are nearing completion.

Both ships are built the same size: Length, 630 ft.; breadth, 73 ft. 6 in.; depth to upper deck, 56 ft. All of the works and houses on the upper deck are shown white in the accompanying photograph. The gross tonnage of each ship is 21,000 tons. Both vessels will be fitted with all modern improvements—electric lights, and bathrooms with hot and cold fresh and salt water. All plumbing is open work, with nickel-plated pipes. The wood finish in passageways and around stair wells is very handsome. Oak, cherry, mahogany, birdseye maple, and cypress are among the woods used.

culatcd through the pipes. By this means the air is cooled before being forced around the openings. The pipes for heating and ventilation are concealed as much as possible. The openings supplying heat are placed near the deck; and those for ventilating are near the ceiling. The ventilation is both natural and mechanical. One particular feature in the heating and ventilation, is that no stateroom is supplied with heat directly. The lower portions of the doors are made of slat work, similar to blinds, but stationary. As every room has an opening for ventilation, the exhaust fans are drawing the air out of the rooms, and, to supply the deficiency in these rooms, the warm air from outside flows in through the slat work in the doors and results in a continual movement, or circulation, keeping the rooms comfortably heated.

He will naturally be anxious to visit the country, which he can do by rail, cutting obliquely across the island from Kingston to Montego Bay, a distance of 114 miles. The scenery is extremely wild, especially that viewed while running through the Cockpit mountains.

It is necessary to take a buggy from Montego Bay, in order to visit the north

Openings arc covered with brass-wire netting, or with face plates, like a register face. The difficulty of heating and ventilating and at the same time having no pipes in sight, can be appreciated only after taking a trip through these vessels.

The immense amount of work in the heating and ventilation of these steamships is shown by the fact that about forty tons of sheet iron was used on each vessel.—H. W. Washisurn, American School Student.

side of the island. The next town in order is Falmouth, which was well laid out but is now in a state of commercial depression. It is hoped that there will be a larger percentage of trade in a short time, as the harbor (which was very dangerous) has been very much improved by blasting and dredging, which is still in the hands of American engineers.

A few small towns of minor importance come next in order, until one reaches St. Ann's Bay, which is built on a decided slope to the sea. Four miles from this town, flows the Roaring river, with its beautiful falls resplendent with spray and white with foam.

The tourist will very likely be anxious to visit Port Antonio, center of the banana industry, the "American town" of Jamaica. This port has shipped thou

The Handiest Thing in the World is

A "iiaal tlf«i*kH If You Have Not Qot a "Desk

3 UcSK If St Gil Watch" You Ought To Get One

They will keep just as (rood time as an expensive watch: can be placed anywhere on your desk, or may be carried in your pocket. Once you find how convenient a desk watch is you will wonder how you ever got along without one. The watch is regular pocket size, full nickeled case, keeps accurate time and runs thirty hours with one winding.

Did You Ever Feel the Need of a Stylo?

A Stylo Is a Pencil that writes with Ink—It Is not a Pen. There is not a man in the world who uses a lead pencil but has wished that it were possible to have a satisfactory pencil that used ink instead of lead. Well, here it is It is not the oldf^hioned stylo with

a stiff needle or spring needle; it has just been patented and placed on the market. It is called the Gravity Stylo,
and its name signifies the principle on which it works. It is only another instance of going back to Nature's laws to
find success. One great advantage about these Stylos is that when left lying on the
desk they are at their best; even if left there for several days without any cap on they
will not leak and will be ready to write the instant the point touches the paper. For
ruling purposes they are unequaled. Ruling done with 5 Stylo is as even and per-
fect as that done by machinery. If you have a Stylo you have a pencil that is
always ready (just like a lead pencil), the advantage being that ink is used.

How Far Do You Walk
in a Day?

Did it ever occur to you that perhaps you walked miles

just going around your shop or office? Perhaps

you'd like to know. If so, get a Pedometer- A

Pedometer is an ingenious affair that goes when

you go and stops when you stop. You put

it in your pocket like a watch (it's smaller

than a watch, too), and when you want to

know how far you have walked, all you

have to do is to look at the Pedometer.

These instruments have hereto-
fore been very expensive, costing

from ten to fifteen dollars,

but this one has just been

placed on the market. It i

not a toy, but an accurate
^ and valuable recorder
'of distance which any
* man will find it worth

while to have.
