It has been said that the American youth has twenty things begun but only one done. This statement is undoubtedly much exaggerated, but it is a fact that too many attempts are made that are never completed. The lack of proper consideration of what is to be done and the means to do it, is probably the chief cause of this condition. It were better not to begin any work than to begin it and not complete it because it is no longer interesting. Should any one find a growing tendency on his part to do careless or incomplete work, every effort should be made to overcome it. The harmful effects of such a practice are many and permanent. A weak and vacillating character ruins many a man, no matter how great his abilities may be. The steady, thorough worker is the one who, in these days of large industrial enterprises, occupies the position of responsibility. This is because he can be depended upon to do what is required of him in the way and when it is wanted. This ability on his part was developed in younger days and became sufficiently characteristic of his work, so that it was recognized and thus procured his advancement. Our young readers who hope to succeed in their chosen vocation will do so only by acquiring the habit of being thoughtful, thorough and persistent in what they attempt now.

The successful transmission of signals across the Atlantic Ocean by wireless telegraphy, which was accomplished by the Italian inventor, Guglielmo Marconi, on Wednesday, Dec. 11, is entitled to rank among the notable achievements of the present century. The success of wireless telegraphy over moderate distances has justified the hope that much greater spaces would eventually be spanned by it, but the sudden leap from transmission over a hundred miles or so to the 1,800 miles distance from Newfoundland to Cornwall, was a surprise to even the most sanguine.

A practical illustration of the use of the telephone as part of a diver's equipment is being given at the exposition which is being held at the Chicago Coliseum this week. A telephone is attached to the helmet of a diver, who is under water for a number of hours. Visitors to the show can converse with the man, and the device is proving quite an attraction. The telephone was used by divers in examining the wreck of the " Idler," a private yacht from Cleveland, which went down on the lakes during the last season, thus enabling the men who were searching for bodies to keep those above promptly informed as to results.
