"OYSTER culture, properly so called, the production of spat by aid of artificial methods, has never been resorted to in this country.” And “ as the scarcity of seed is one of the greatest difficulties now encountered by the oyster planter, this subject offers an interesting field for investigation.”
THERE is a delightful child’s story, known by the title of Jack and the Bean-stalk, with which my contemporaries who are present will be familiar. But so many of our grave and reverend juniors have been brought up on severer intellectual diet, and perhaps have become acquainted with fairyland only through primers of comparative mythology, that it may be needful to give an outline of the tale.
ONE of the questions considered by Laplace in the early part of the century, and which he thought of sufficient interest to have a place in his System of the World, has dropped almost wholly out of view. I refer to the relation of the moon to the earth—what it is and what it might have been.
THE facility with which a high temperature may be obtained with electricity, and the heat controlled and located just where it is wanted, makes this agent peculiarly well adapted to the heating of metals for welding and forging purposes. This was early recognized by Prof. Elihu Thomson, to whom the development of the art is chiefly due, and who has devised a great variety of apparatus capable of performing all classes of work, from the simple welding of two wires to the making of large and complicated joints.
IN the May number of The Popular Science Monthly is an article by Prof. W. W. Aber, entitled The Oswego State Normal School, in which the writer claims for that institution the credit of introducing and promulgating over the country the system of teaching known as the Pestalozzian system.
AT a recent meeting of prominent educators in Boston to consider means of promoting work in elementary science, a well-known professor of science said that there was danger that college professors would make out a scheme for teaching science and impose it upon the elementary schools; that the work was likely to be begun at the wrong end.
IN crossing the seas, as in walking through the fields, there is always the anticipation of making some new discovery. Today Nature may reveal to us some long-withheld secret. This illusive bird or wild flower which we hitherto missed we now meet face to face.
THERE are numerous evidences showing that the same aboriginal peoples who named the waters of North America coined also the prehistoric geographical titles in South America. Scores of actual identities are revealed in the prehistoric nomenclatures of the two portions of this continent.
THE Material View of Life and its Relations to the Spiritual, by Prof. Graham Lusk, Assistant Professor of Physiology, Yale Medical School, in The Popular Science Monthly for August, 1893, presents to the mind of a layman a unique combination of facts and fancies, of scientific deductions and metaphysical as sumptions.
WHY is it that the business men of to-day find so much fault with the chirography of the boys who are seeking, or have obtained employment? They assert with great positiveness that the average boy of thirteen or fourteen years does not write legibly; that his labored copy-book hand, with its pale and sightdestroying hair-lines, is not at all adapted for business purposes.
I DO not write this paper with the intention of converting or even convincing anybody, for nobody is more impressed with the great truth that what is good for one person is not good for all. The infinite individuality of the human race is what distinguishes it from animals.
IT has been assumed that the evaporation off the Gulf of Mexico furnishes the most part of the rainfall of the great valley. Says an authority, when speaking of that of the whole country, “ By far the greater portion comes from the gulf and spreads over the central and eastern part of the Mississippi Valley, and even much of the Atlantic slope.”
MATHEMATICAL CURIOSITIES OF THE SIXTEENTH CENTURY.
M. V. BRANDICOURT
IN the great intellectual revival of the sixteenth century, mathematics as well as letters and the arts were recuperated first from the pure sources of antiquity. Casting away poor Latin translations, second-hand versions through the Arabic, on which the Middle Ages had fed, geometricians emulated one another in zeal for learning the Greek language, in order that they might read in the original text the works of Euclid, Archimedes, Ptolemy, and Diophantus.
WE put animals under all sorts of contributions, taking even their lives for our necessities, pleasure, and caprice, without once considering what their views may be of our proceedings or of us, or whether they have any views. We need not doubt that they have views, and some very definite ones.
THE arts of marine engineering and naval construction have been revolutionized through the inventions of Captain Ericsson. As is remarked in a passage cited by Mr. F. C. Church, in his biography of him, “in the closing years of his life he could look back upon 'a change in the physical relations of man to the planet on which he dwells, greater than any which can be distinctly measured in any known period of historic time,' and this he had no small part in creating.”
THE BEARING OF THE DOCTRINE OF EVOLUTION ON SOCIAL PROBLEMS.
SCIENCE AT THE COLUMBIAN EXPOSITION.
THE following very pertinent questions were proposed for discussion at the World’s Congress of Evolutionists, held during the last days of September in connection with the Columbian Exposition: “Does the doctrine of evolution in its sociological aspects offer wise suggestion for the solution of the grave social and economic problems of our time?
IT is the duty of the Department of Labor to provide for reports, at intervals of not less than two years, on the general condition, so far as production is concerned, of the leading industries of the country. A shorter period is prescribed than that fixed for the taking of the census, in the belief that a fairer average would be shown in the run of consecutive reports of short terms than could be obtained from reports made every ten years, any two or more of which might be, relatively to the intervening years, exceptional ones.
Spencer’s Education in English Training Colleges.—For several years Herbert Spencer’s book on Education has been a text-book in the schools of England and Wales which correspond to normal schools in America, and has been very highly appreciated.
Polygonum sakhalice is the name of a forest plant from the island of Sakhalien, Japan, of which flattering accounts are given by M. Doumet Adanson, who has cultivated a few stools of it in France. He got it as an ornamental plant, and it is really very handsome.
