Note 39 — PART I. TEACHERS' LEAFLETS. (continued 6)

Note.—Common ink will not answer for this purpose because it "runs" when the root is wet; indelible ink, used for marking linen or for drawing, should be used. It should also be said that the root of the common pumpkin and of the summer bush squashes is too fibrous and branchy for this test. It should be stated also that the root does not grow at its very tip, but chiefly in a narrow zone just back of the tip; but the determination of this point is rather too difficult for the beginner, and, moreover, it is foreign to the purpose of this tract.
