Unstamped letters can also be posted in this very delightful box, and special delivery stamps can be secured by stating on the blank the number of letters that are to be stamped, and enclosing the money for the same in the special envelope.

All unstamped matter is turned over to the clerk who has charge of the envelope department. He buys the stamps, sticks them on, and despatches the letters.

This service is only rendered to people who buy their own boxes.

The post-office does not undertake to furnish them, but only to give good service with them when they are purchased.

A wonderful feat of swimming has just been performed in England.

A man named McNally, a champion swimmer, and a native of Boston, Mass., has attempted to swim across the English Channel from Dover, England, to Calais, France, a distance of thirty-five miles.

This body of water is the most uncertain and the roughest of seas.

Many people who are fine sailors and have made many voyages to Europe say they would rather cross the Atlantic than the English Channel.

The reason for this is that the vast body of water which forms the North Sea, in forcing its way between the narrow straits of Dover, is driven into short cross-waves and currents, which make the sea always choppy and rough.

Many swimmers have made the attempt to swim this Channel before, among them Boyton, and Captain Webb who lost his life in an attempt to swim the Niagara Rapids.

No one has so far achieved success.

McNally succeeded in reaching within three miles of the French coast, but he was then so exhausted that he had to be pulled into the boat and give up the attempt.

He had announced that he would swim the Channel, and had been some days in Dover, swimming over a part of the course, and getting himself in training for the final effort.

He started from the Dover pier, followed by a row-boat in which were two sailors, a newspaper man, and his trainer.

When he started out he had no intention of taking the swim. He merely went out for exercise. The weather was so foggy that his companions urged him to turn back and exercise later in the day.

He, however, kept on, and when he was about six miles from the shore the fog lifted, and wind and tide all being in his favor, he determined to make the trial then and there.

He was in the water fifteen and a half hours, and swam steadily all the time at the rate of about a mile and a half an hour.

Swimmers will be interested to know that McNally used the breast stroke continually, only occasionally changing to a side stroke for relief.

He never swam on his back. He says that this method of swimming interferes with the muscles, and gets them out of condition for resuming the breast stroke.

Swimmers as a rule seek rest and relief by turning on their backs, so the opinion of an expert on such a subject is well worth having.

Apart from the interest we all feel in great feats of strength and endurance, such an attempt as that made by McNally is valuable to us, as it shows us the length of time it is possible for a swimmer to remain in the water without becoming exhausted.

Swimming is an accomplishment that every boy and girl should acquire, and the knowledge that if a swimmer keeps cool, and has his wits about him, he can remain in the water for a considerable period without danger of drowning, should be taken to heart by every lad and lass who contemplates boating as a part of the summer's enjoyment.
