332 Observatory, at the Lick, Yerkes, Flower, Dudley and other establishments, are the best evidence of success. This book marks an epoch in the history of practical astronomy in America and has more than a passing value. A country that has produced the object-glasses of the Clarks and of Brashear, the sextant of Godfray, the zenith-telescope of Talcott, the chronograph of the Bonds, the break-circuit chronometer of Winlock, the diffractiongratings of Rutherfurd and of Rowland, the mountings of Warner and Swasey—to say nothing of many minor inventions and devices—has already taken the highest place in one important field. Who can doubt that the next century will see a corresponding progress in other branches of astronomy? The oldest science may yet find its chief center in the youngest country.

annual report of the Secretary of Agriculture has come to be regarded as of special interest to men of science, inasmuch as it is devoted very largely to a resume of the scientific investigation which is being carried on under his direction. The high appreciation which Secretary Wilson has of the economic value of investigation along lines related to agriculture is evidenced by his cordial support of such work, and the spirit of inquiry which he has inspired throughout the Department. His practical experience as a farmer and his active connection with experiment-station work before coming to the Department have made him quick to see the application of a new discovery and have enabled him in many instances to suggest new lines of inquiry. The result has been a wider appreciation of the department as an institution for research, and the securing of greatly increased financial support from Congress for its development along this line. It is now recognized by those familiar with it as being one of the largest and best equipped institutions for organized research in this country, and in the special lines in which it is engaged it occupies a leading position. Some of the newer features which Secretary Wilson mentions are experiments in plant breeding, directed toward the production of hardier orange hybrids for the Southern States and corn of earlier maturity and more resistant to drought and smut; studies of the true cause of the fermentation of tobacco in curing, which have suggested important modifications of the old method of handling; experiments in growing Sumatra tobacco in the Connecticut Valley, with the aid of shade, and the Cuban types of cigar-filler in Texas, the indications for the success of both of which are now considered very promising; the extensive preparation and testing of serums for combating hog cholera and tetanus or lockjaw, and of vaccine for the disease known as blackleg; field and laboratory studies of plants supposed to be poisonous to sheep on the Western ranges, to determine the actual causes of the heavy losses of stock, and to find remedies for poisoned animals: and the investigation of a number of the more troublesome plant diseases, among them diseases of the sugar beet, which are reported to have caused a loss of over two million dollars in California.

Department's policy of sending explorers to various parts of the world to search out new plants or varieties likely to prove valuable in this country has already resulted in a long list of promising introductions, including especially the Kiushu rice from Japan, which, it is believed, will insure the success of the rice industry in this country, and varieties of wheat from Russia, Hungary and Australia, which are superior in milling qualities, resistance to rust and yield. The successful introduction into California of the insect which fertilizes the flowers of the Smyrna fig, resulting the past season in the production of six tons of these figs of the highest grade of excellence, promises the development of another important industry. Among the larger
