Introductory Statement

Before men thoroughly understood the reproduction of plants from seeds, it was thought that any kernel of corn which appeared to be of good size and shape would be satisfactory for seed purposes. It has been proven that while we may be able to judge most of the qualities of a kernel of corn by examining it, we cannot always definitely tell about its vitality.

Seed Corn Tester Specifications

The Side Pieces

Plane one edge of each of the side pieces perfectly straight and square (Chapter II., Paragraph 4). Prepare a working end (Chapter II., Paragraph 5). Lay out the dimensions of the side pieces and cut them, making sure that the opposite sides are exactly the same length and width. In like manner square the stock and prepare the two end pieces.

The Bottom

The bottom is to be made up of narrow strips, and as the box is to hold moist dirt or sand, it will not be well to fit the joints too closely, as they must have room to swell. It will not be necessary to joint the edges of the strips which are to form the bottom. Nail together the two sides and the two ends, forming the frame. Cut the pieces for the bottom just long enough to fit snugly inside the frame. Put in a sufficient number of strips to make a solid bottom. Nail through the side pieces into the ends of the bottom pieces.

The Legs

Square the stock (Chapter II., Paragraphs 2, 3, 4, 5). Lay out, and make pieces the dimensions for the legs, as shown in the drawing. Notice that the two rear legs extend above the box to form a rack on which to hang the seed corn racks. Fasten the legs in position by nailing through them into the box, and by nailing the edges together, "pig trough" fashion.
