When a lad of twelve years, Col. Edgerly removed with his parents to Manchester. He attended the public schools for a time, but at an early age entered the service of the Amoskeag Manufacturing Company, being engaged at first in the mills and afterwards in the machine-shop; but, after several years, becoming dissatisfied with the dull routine of mechanical labor, and desirous of testing his powers in the field of business, in October, 1856, at the age of twenty-three, he embarked in trade as a joint proprietor of a drug-store with Mr. Lewis H. Parker. He was thus engaged but a short time, however, removing the following year to the town of Pittsfield, where he soon established himself in the insurance business, taking the agency of various companies, fire and life. This, it may be truly said, was the actual starting point in his career. He found in this business a field of labor congenial to his tastes, and peculiarly adapted to the development and exercise of the distinctive powers of mind and body with which he is endowed; and he entered into his work with heart and soul. He was not long in discovering the special line of effort to which he was best adapted, and which gave the best promise of substantial success in response to such effort; nor were the managers of the business in question long in ascertaining, from the character of the work already accomplished, the direction in which their own advantage lay; and so it came about in a short time, that after a visit to the company's office in Springfield, made upon the solicitation of the president, Col. Edgerly became exclusively the agent of the Massachusetts Mutual Life Insurance Company, relinquishing all other agencies, and devoting his entire efforts to the interests of the company. So thorough and satisfactory was the work which he accomplished, that a year later he was given the general agency of the company for the state of New Hampshire, with headquarters at Manchester, to which city he removed with his family, when, in 1863, he was given charge of the business for Vermont and northern New York in addition to this state. Under his efficient management and supervision the business of the company increased to a remarkable degree in the entire territory of which he had control, until the net annual receipts in premiums upon new policies, in New Hampshire alone, had risen from substantially nothing in 1859, when he first commenced work, to nearly seventy-five thousand dollars in 1866, representing the proceeds from the issue of a thousand policies, covering an aggregate insurance of more than a million and a half of dollars. This remarkable success was due, not simply to the work of personal solicitation, in which line Col. Edgerly has no superiors, but more especially to the keen discernment and ready knowledge of men with which he is endowed, enabling him to select proper agents and judiciously supervise their work.
