Sport, pastime, enjoyment seem to engross the minds of many of the young men of today to the almost entire exclusion of anything else. While these are right and proper, even beneficial in their way, there are limitations, and these limitations require that the probable future vocation should receive consideration, and a reasonable portion of time be given for preparation toward it. In view of the increasing number of capable young men in situations unsatisfactory to themselves, a brief study of the causes leading thereto is instructive. In general, it will be found that during youth and early manhood no great attention was given to obtaining an adequate knowedge of some trade or business. Therefore the business career is commenced with no substantial foundation. Adverse circumstances, in such a case, are productive of disastrous consequences, the worker not having attained to that skill, or acquired the knowledge for which there is always an unsatisfied demand.

It is, therefore, of decided importance to the future prosperity of every youth that he, early in life, forms definite conclusions as to the general trend of his future business career, and thenceforth utilizes every available help which presents itself. Only in this way can he reach the position of being better than the ordinary; that is, the man who is wanted, instead of wanting.

The man who knows something thoroughly, can do something well, is the man who arrives.

During the months of July, August and September an extra one-subscription premium will be given to anyone sending in three subscriptions. As many of our readers will, during this time, be enjoying their vacations, they should find it easy in this way to obtain some valuable additions to their tool kits.

We will also during these months give to anyone sending $1.25, a year's subscription to Ama-tuer Work and a choice of either of the following books:Norrie's "Induction Coils " or Avery's "A, B, C of Dynamo Design." The first of these books contains much of value to those interested in coil making ; the latter book is undoubtedly the best presentation of the elementvry principles of the subject to be obtained and just the book for amateur dynamo and motor builders.

The "poison squad" utilized by Dr. Harvey W. Wiley, chief chemist of the American Agricultural Department, in experimenting with adulterated food products, was disbanded on May 21. The twelve young men have eaten nothing but adulterated food since early in January. Everything has been more or less tinctured with salicylic, sulphuric or benzoic acid. The experiments were a continuation of those begun a year ago to determine exactly the actual effect of food preservatives on the human system. Such acids were used as are employed by domestic aud foreign packers in preparing meats, butter and other products for shipment. The acids were at first placed in the food, but subsequently given in capsules. The most accurate record was kept of the men's condition. It is said some of the men have materially deteriorated in health as a result of the acids administered to them. All are said to have been affected by the drugs used as food preservatives. No details as to results will be given out until a formal report is submitted to Congress.

A narcotic bomb has been invented by a surgeon in the Austrian army. The bomb, which may be fired from any gun, has a time fuse, and when dropped among a regiment Of the enemy will not explode, but will fill the air with narcotic gases strong enough to make 2000 men unconscious for several hours. While in this condition they may be captured, and when they wake up they will feel no bad effects of their experience beyond a slight headache.

The whirling winds of Arabia sometimes excavate sand pits to the depth of 200 feet, the rim usually being three times that length in diameter. A sand pit thus may be entirely obliterated in a few hours and another excavated within a short distance of it.
