SONG OF BLOSSOM TIME (courtesy of the independent.) What is the song; of the frog- in the marshes? What arc the tidings the blithe robins teach? Let us be merry with the bloom of the cherry. Let us be gay with the bloom of the peach! “Let us go out where, on ripples of rapture, All the sweet odors of earth are afloat.— Glad in the gloaming, let us all be homing. Back to the mate, with a song in the throat! Back to the friends, that have sued for our presence. Back to the loves that have let us aspire. Back to the dreaming, ay. and to the gleaming Fair of the flashes of life’s hidden fire!” What is the gospel of Jack-in-the-pulpit ? What is the glory the orioles reach ? “Let us be merry with the bloom of the cherry, Let us be gay with the bloom of the peach!” Marguerite Ogden Bigcloiv, (Mrs. James G. Wilkinson.) PAGE EIGHT

IX the ordinary geometry of space of three dimensions. a solid is defined as a portion of space separated from the remainder of space by a surface. This surface. if in parts(e. g. the surface of a prism) has its parts Innind by lines, which, in turn, arc limited by points, the vertices of the solid. Surfaces and lines may l e unlimited or unbounded, and yet finite in extent: as. for example, the surface of a sphere and the circumference of a circle. The point is considered to have no size or dimension ; the straight line one dimension, length, which makes direction | ossi-ble: the Hat surface two dimensions, length and width, and the solid three dimensions. length, width and thickness. If a point moves in a certain way its path is a straight line which has one dimension. iength. due to the motion of the dimensionless point. If a straight line moves in its own direction, its path will be the same line, except that a limited line will increase its length: but if it moves in a direction not its own. say in one perpendicular to its own. the path it passes through is a plane surface, having two dimensions, length, belonging to the generating line, and width, due to the motion of the line in the new direction. I f a flat surface moves in one of its own directions. no change is produced, except that a limited surface will increase its extent; but if a flat surface moves in a direction not its own. say one perpendicular to both its own dimensions, its path is a solid, having three dimensions, the length and the width of the generating surface, and thickness, due to the motion in the new direction. For example, a one-inch cube may l e produced by conceiving first a point to move one inch in any direction, second, the resulting line to move one inch in any direction at right angles to its own. and third, the resulting square to move one inch in the direction at right angles to both its own. Thus it is evident that by the motion of a point, a line, or a surface in a new direction, a new figure can be produced having one more dimension than the generating figure. Xow if a solid could move in a direction not its moil, say one at right angles to all its three dimensions, wc conclude by analogy that a new figure would be formed having four dimensions. This wc cannot picture because wc arc lxnind down in our mental images to the material furnished us by our senses. That is, our images of figures in space arc based wholly on our sense impressions of matter; hence we may lx conditioning space by assuming for it characteristics which belong to matter. A four dimensioned solid may only seem impossible, and not be so in reality. Suppose that triangles A and l (Fig 1) in the same plane have their respective parts equal and arranged in the same orders, i. c. angles 1. 2. 3 and sides a, b. c, are arranged around clockwise in both; that is, they arc the same side up.
