Note large development of upper portion of head; slight squareness of jaw; height of head above temples, especially in center; fine texture; excellent balance of features, and calm, poised, thoughtful, but kindly expression.]

Said to be one of the greatest living authorities on plant culture. Slight squareness of build indicates tendency to interest in out-of-door matters, which, on account of large development of mental qualities, he expresses in an intellectual way.]

We have seen a boy take a penny to school, buy a slate pencil or a lead pencil with that penny, and trade that for an old pocket knife, the knife for something else, and keep on swapping until he had a gun, a set of chess, a bag of marbles, and several other important boys’ acquisitions, all from that one penny. Another boy takes penny after penny to school and he never has anything to show for it You know such boys—and grown people, too. Every individual has some such aptitudes—either latent or developed, either mediocre or marked—and his aptitudes fit him better for some one vocation than for any other.
The sixth point to be considered is experience. One might be fitted for a vocation with all of the five points that we have enumerated, and yet not have either the education or the training for it. What shall he do? Theoretically and ideally, every individual should be carefully and thoroughly trained, from his earliest childhood, for the vocation for which he is physically, mentally, and morally fitted.
