"Protection Against Tornado?s," by Lieut. John P. Finley; as 

 well as articles by Simon Sterne, Edward Everett Hale, James E. 

 Murdock, M. J. Savage, and Alice E. Ives. 



— The Religious Tract Society of London, believing that due 

 care of the body is as much a Christian duty as concern for the 

 soul, makes it an important part of its work to diffuse sound in- 

 formation, in a popular and readable form, in such a way as to 

 lead people to use all the means in their power to preserve their 

 own health and the health of those dependent upon them. With 

 this object in view, the society has issued a neat little volume en- 

 titled "Health at Hoaie Tracts," vvritten by Alfred Schofield, 

 M.D. The book is made up of a dozen tracts which had previ- 

 ously been issued separately, and which had. been so well received 

 by the public that their publication in the present form was de- 

 termined upon. Fleming H. Revell of New York and Chicago 

 represents the Tract Society in this country. 



— It appears from a publication recently issued by the Govern- 

 ment Statistician of New South Wales that many descriptions of 

 gems and gem stones have been discovered in various parts of the 

 Australian colonies, but no systematic search has been made for 

 any but the diamond Diamonds are found in New South Wales, 

 Victoria, and Queensland, but only in the first-named colony have 

 any attempts been made to work the diamond drifts. The prin- 

 cipal diamond fields are situated at Bingera, near Inverell, in the 

 New England district The Government of New South Wales 

 has, on various occasions, obtained the services of experts to re- 

 port upon the fields, as well as the gems which have been from 

 time to time extracted from them, and these reports, it is said, 

 have generally been of an encouraging nature. The number of 

 diamonds found in the colony to the end of 1887 is estimated at 

 75,000, the largest one being of 5| carats, or 16.2 grains The 

 diamonds occur in old tertiary river drifts, and in the more recent 

 drifts derived from them. The deposits are extensive, and have 

 not yet been thoroughly prospected. The New South Wales 



diamonds are harder and much whiter than the South African 

 diamonds, and are classified on a par with the best Brazilian gems. 

 During the year 1887 the diamond companies at Cope's Creek, 

 near Bingera, produced about 23,000 diamonds, weighing 5,151 

 carats; but in 1888, owing to the severe drought which occurred, 

 the search for diamonds had to be temporarily abandoned. 



—The September number of the New England Magazine will 

 be strong in agricultural articles. James Knapp Reeve tells of 

 the advance of agricultural schools, and traces back the history of 

 agricultural education. Another paper in this series gives an in- 

 teresting treatment of the present condition of the farmer, while 

 an article with the title " Moses in Massachusetts'' cannot fail to 

 stir up interest, especially among the readers of Henry George. 

 The Neir England Magazine is bent upon honoring the South. 

 The University of Georgia comes second in her series of illustrated 

 articles on the colleges of America, and is presented by Charles 

 Morton Strahan in this number with a series of engravings. 



—In Lippincott's Magazine for September, Rear-Admiral Dan- 

 iel Ammen, one of the chief promoters of the Nicaragua Canal 

 scheme, contributes an article which gives a history of the incep- 

 tion of the project and the progress made up to date, and indicates 

 the results which will accrue from the construction of the canal. 

 A timely article upon " Current Concentration of Industrial Capi- 

 tal " is contributed by Henry Clews. He inveighs in strong terms 

 against the present '■ trusts " and "combines," and predicts their 

 speedy downfall. He holds, however, that some form of combi- 

 nation is necessary to all large enterprises, and that existing State 

 laws relating to corporate enterprises need but to be broadened in 

 their scope, and more strictly defined in respect to their safe- 

 guards, in order to keep all combinations within proper bounds. 

 Alfred C. Haddon gives some interesting descriptions of various 

 dances he witnessed among the Papuans of Torres Straits, and 

 Charles Mcllvaine (Tobe Hoge) has an entertaining article upon 

 " Superstitions about Birds."

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists of Europe and America, and bringing them 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of "one remedy for one 

 disease" must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bottle, and the use of which, as statistics prove, 

 kas > tiineii more stomachs thati alcohol. A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors.
