Borrowing his figure of speech from the environment of child-hood, C. J. Weber has said: "_Die Gesellschaft ist die Grossmutter der Menschkeit durch ihre Töchter, die Erfindungen_,--Society is the grandmother of humanity through her daughters, the inventions," and the familiar proverb--Necessity is the mother of invention--springs from the same source. Isaac Disraeli aptly says: "The golden hour of invention must terminate like other hours; and when the man of genius returns to the cares, the duties, the vexations, and the amusements of life, his companions behold him as one of themselves,--the creature of habits and infirmities," and not a few of the "golden hours of invention" seem to belong to the golden age of childhood. Even in these "degenerate" days the child appears as an inventor. A contributor to the periodical literature of the day remarks: "Children have taken out a number of patents. The youngest inventor on record is Donald Murray Murphy, of St. John, Canada, who, at the age of six years, obtained from the United States exclusive rights in a sounding toy. Mabel Howard, of Washington, at eleven years, invented an ingenious game for her invalid brother and got a patent for it. Albert Gr. Smith, of Biehwood, Illinois, at twelve years invented and patented a rowing apparatus" (_Current Lit_., K T., xiv. 1893, p. 138). The works of Newell (313), Bolton (187), Gomme (243), amply reveal the riot of childish variation and invention in games and plays. Mr. Newell observes: "It would be strange if children who exhibit so much inventive talent [in language] did not contrive new games; and we find accordingly that in many families a great part of the amusements of the children are of their own devising. The earliest age of which the writer has authentic record of such ingenuity is two and a half years" (313. 25). And among the primitive peoples the child is not without like invention; some, indeed, of the games our children play, were invented by the savage young ones, whose fathers have been long forgotten in the mist of prehistoric ages--the sports of their children alone surviving as memorials of their existence. Theal tells us that the Kaffir children, when not engaged in active exercise, "amuse themselves by moulding clay into little images of cattle, or by making puzzles with strings. Some of them are skilful in forming knots with thongs and pieces of wood, which it taxes the ingenuity of the others to undo. The cleverest of them sometimes practise tricks of deception with grains of maize" (543. 221). The distinguished naturalist, Mr. A. R. Wallace, while on his visit to the Malay Archipelago, thought to show the Dyak boys of Borneo something new in the way of the "cat's cradle," but found that he was the one who needed to learn, for the little brown aborigines were able to show him several new tricks (377. 25).
