Dans les premiers jours de la colonisation américaine, c'est douteux, déclare le professeur John Fiske, si nos ancêtres auraient pu rester ici elle n'avait pas été pour com indiennes. Pas de labour, ni même de compensation était nécessaire pour la réussite de la mobilisation de ces céréales. Les arbres furent annelés, donc tuer leurs tops pour laisser à la lumière du soleil ; la riche terre était égratigné un peu avec un outil primitif, et les semences mises en et couverts ; et les plantes qui poussent là

In those early days of American colonization, it is doubtful, says Professor John Fiske, if our forefathers could have remained here had it not been for Indian com. No plowing, nor even clearing, was necessary for the successful raising of this grain. The trees were girdled, thus kill- ing their tops to let in the sunlight; the rich earth was scratched a little with a primitive tool, and the seed put in and covered; and the plants that grew therefrom took care of themselves. It the pioneers had been obliged to depend alone upon the wheat and rye of Europe, which only grows under good tilllage, they might have starved before they gained a foothold on our forest-covered shores. The Corn Plant In studying the maize it is well to keep in mind that a heavy wind is its worst enemy; such a wind will lay it low, and from such an injury it is difficult for the corn to recover and perfect its seed. Thus, the mechanism of the corn-stalk and leat is adapted for prevention of this disaster. The corn-stalk is, prac- tically, a strong cylinder with a pithy center; the fibres of the stalks are very strong, and at short intervals the stalk is strengthened by hard nodes, or joints, il the whole stalk were as hard as the nodes, it would be inelastic and break instead of bend; as it is, the stalk is very elastic and will bend far over before it breaks. The nodes are nearer each other at the bottom, thus giving strength to the base; they are farther apart at the top, where the wind strikes, and where the bending and bowing of the stalk is necessary. The leaf comes off at a node and clasps the stalk for a con- siderable distance, thus making it stronger, especially toward the base. Just where the leaf starts away from the stem there is a little growth called a rain-guard; if water should seep between the stalk and the clasping leaf, it woul
