Your Secretary is often petitioned for the Entomological Report, which he must needs send with the whole bound Report of the Board, and thus incur unnecessary expense; or else not send at all.

Excerpt from Parasitic and Predaceous Insects in Applied Entomology It is quite different in the second method Of dealing with beneficial insects, for here man has an Opportunity Of doing some very effective work, and it is only within comparatively recent years that the impor tance of this particular phase of the subj ect has been fully realized. The Rev. C. J. S. Bethune, Of Canada, was probably the first entomologist to suggest, in one of the earlier volumes of the Canadian Farmer, the importation of the European parasites Of the Wheat Midge (diplosis tritici) into America, on the supposition that this cosmopolitan species might thus be kept in check on this continent to the same extent that it was in Europe. SO far as I am aware, the attempt was never actually made, and though some subsequent correspondence was entered into between Fitch and Curtis, and later between Walsh and some of his English friends, nothing tangible resulted. The matter was, In fact, never seriously studied with this purpose in View. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

He reaches the conclusion that' hardening is more useful in short-bar magnets than in needles, and that boring a hole in the centre of the magnet is, in general, hurtful. J. Trowbridge, of Harvard, demonstrates experimentally that by distributing the fine wire of an induction coil upon two straight electro magnets (instead of one), whose poles are provided with armatures con sisting of bundles of thin, soft iron plates, the strength of the spark is increased 400 per cent.

Excerpt from The Yucca Moth and Yucca Pollination Under direction of the Board of Trustees of the Missouri Botanical Garden, its third annual report is presented to the public. As best calculated to promote the objects of publication, the difiusion of information concerning the institution and of the results of scientific work done in connection with it, it has been decided that an annual volume shall be issued in the early part of the year, con taining the official report of the President of the Board and the Director of the Garden for the preceding year, to gether with such other matter as is considered pertinent. These volumes are primarily intended for distribution to botanical gardens, learned societies, and other scientific institutions, whose publications are desired in exchange; but when reason exists for it, they may also be sent to public libraries, or to individuals, although as a rule the latter cannot be carried on the regular mailing list for this purpose.

Charles Valentine Riley, the son of Charles and Mary Valentine Cannon Riley, was born on September 18, 1843 in Chelsea, London, England. His father, a clergyman of the Church of England, died during his childhood; his mother married a second time.
He was sent to boarding school at Dieppe in France and later to Bonn in Germany. He was passionately fond of natural history and of drawing and painting. He collected and studied insects and sketched them in pencil and in color. At both Dieppe and Bonn, he carried off first prizes in drawing and he was urged by his drawing master in France to devote himself to art studies in Paris. Financial trouble at home caused him to leave school at the age of seventeen, and he came to the United States.
He reached Illinois and settled upon a farm about fifty miles from Chicago, of which George H. Edwards was the owner. Here his attention was drawn to insect injuries to crops, and he sent accounts of his observations to the Prairie Farmer.
At the age of twenty-one he moved to Chicago and became connected with this leading agricultural journal as a reporter and artist and as editor of its entomological department.
He enlisted in the Union army toward the close of the Civil War and served until his regiment (the 134th Illinois Volunteers) was disbanded in November 1865. His writings attracted the attention of B. D. Walsh, the state entomologist, with whom he collaborated, and partly through Walsh's influence he was appointed in the spring of 1868 to the newly created office of entomologist to the State of Missouri.
From that time until 1877 he was engaged in his Missouri investigations, which thoroughly established his reputation. He published nine annual reports, which have become famous. His careful work on life histories, his very beautiful drawings on wood, which were engraved and used as illustrations to his text, and his knowledge of agriculture made an admirable combination.
Many authorities date the modern science of economic entomology from the time of the publication of these reports.
During the years 1873 to 1877 many of the Western states and territories were invaded by armies of grasshoppers from the Northwest. Riley studied this plague with the originality and vigor which characterized his work, and in his last three reports he published a mass of important results. In the meantime he worked vigorously to bring the grasshopper scourge to the attention of Congress and succeeded in March 1877 in securing the passage of a bill creating the United States Entomological Commission, of which he was appointed chief, with A. S. Packard, Jr. , and Cyrus Thomas as his associates.
In the spring of 1878, while the first report of the Commission was going through the press, Townend Glover was retired as entomologist to the United States Department of Agriculture, and Riley was appointed his successor.
He held this position for nearly a year, and then resigned, owing to a disagreement with the commissioner of agriculture.
Two years later he was reinstated, and remained the chief of the federal entomological service until June 1894. The service was made a division of the Department of Agriculture under his administration, and grew in size and importance.
His annual reports were practical and of high scientific value.
He began the publication of the journal known as Insect Life, which was continued from 1889 to 1894 and received very general praise. Years before, in 1868, he had begun with Walsh the publication of a journal known as the American Entomologist. Their association was interrupted by Walsh's death, but Riley continued the publication during its second volume. Then, after years of silence, a third volume was published under his editorship in 1880.
He was a man of means, and resigned from office in June 1894, intending to spend the rest of his life in research work in the National Museum, where he held an honorary position; but he was killed in September 1895 by a fall from his bicycle.
He had the degree of Ph. D. from Washington University in St. Louis, but, although he had never held a university position, he was generally known as "Professor Riley. "
Riley received many honors during his life and was decorated by the French government for his work upon the grapevine Phylloxera. His published work shows an unusual sense of economic proportion combined with scientific accuracy and a keen insight into biological matters. His extraordinary observations on the relations between the Yucca moths and the fertilization of the plants of the genus Yucca attracted great attention; and his observations on the hypermetamorphoses of the blister beetles drew to his work widespread attention among scientific men. Very many other problems were illuminated by his investigations. His bibliography was very large; in 1889 it had reached 1657 individual titles and 479 in co-authorship with B. D. Walsh; additional papers to the number of 364 were published in co-authorship with L. O. Howard, and he continued to publish down to the time of his death.
