Though assiduous in the pursuits of agriculture, his benevolent instincts led him to take an active interest in the causes of temperance, anti-slavery, and whatever else the public welfare seemed to demand. His efforts in this direction, in co-operation with those of others, produced a change in the politics of the town, which resulted in his introduction to public life. He was elected moderator of town-meeting fourteen times, selectman six times, and to the legislature three times. In all these trusts he showed himself wise, able, and efficient. As a legislator, he did not seem anxious merely to shine, but to be useful, and to advance the interests of the state. Such qualities and service commended him to public favor, and in 1862 he was elected a councilor for the last year of Gov. Berry's administration, and re-elected to the council of Gov. Gilmore. This, it will be remembered, was while the hardships and horrors of the civil war were upon us, and when questions that could not be settled by precedent, and that tested the authority and resources of the state, were brought daily before the governor and his council for decision. The exigencies of the government would not suffer delay. Not only great permanent interests, but the very life of the nation was in peril, and large and frequent demands were made upon the states for supplies of men and money, when every resource seemed exhausted. In such times means must be invented and resources created. Criticism becomes silent, and waits for the return of peace to awaken into unreasoning activity. Under the pressure of such events, weak men are likely to be paralyzed, avaricious men corrupt, and bold men to abuse power.

The qualities which Mr. Pillsbury developed in these trying circumstances ought to make his name historic. The writer has received communications from two gentlemen who were associated with him in the council, and whose services to the state are universally acknowledged, and, as they express more forcibly than any words of mine can do the part which the subject of this sketch took in that eventful period, I take the responsibility to publish such portions of their respective letters as bear specially upon the subject of this paper. The known character of the writers will give additional weight to their strong language of encomium. Hon. John W. Sanborn, of Wakefield, writes, as follows:—

"Learning that you are to prepare a biographical sketch of Hon. Oliver Pillsbury, I take pleasure in saying that I formed acquaintance with him in 1863, being then associated with him in Gov. Gilmore's council. His great executive ability, patriotism, honesty, and integrity won the respect and admiration of all his associates. At that time the country was engaged in that terrible war for the support of the government and its own salvation, and grave questions came before us relative to the prosecution of the same. Although an ardent Republican, he never let partisan feelings warp his judgment in his official acts. He had strong convictions of right, but was always ready to discuss all questions with that frankness and fairness which characterize men of noble minds, and he fully appreciated the opinions of his opponents. I had the honor to serve with him on the military committee of the council, which had important matters to consider,—questions involving the rights and interests of the soldiers, their families, and the state. The duties of this committee were arduous and often difficult, but I can attest to the fidelity and untiring energy with which he performed his part. He took great interest in the welfare of the soldiers, particularly the sick and wounded, and was ever ready to minister to their wants. In a word, he was a model councilor for the time in which he served, and the future historian will class him among our ablest and most efficient men."

Hon. John W. Noyes, of Chester, who was also in official association with Mr. Pillsbury, says:—

"I was with him a very considerable portion of the time for two years, while we were members of Gov. Gilmore's council, during the war. He was the most important member of the council, on account of his past experience and familiarity with the duties of the situation; in fact, his information and judgment were exceedingly valuable to the governor, and all the other members of the council.

"I regard Mr. Pillsbury as one of the best-informed and most competent business men in this state. I hardly think that there is another man in the state that could fill his present position as well as he does. I told Gov. Stearns before he made the appointment, that, if he knew Mr. Pillsbury as well as I did, he would not need recommendations, but would urge his acceptance of the place."

It would be idle to add anything to such commendations.

In 1869, Mr. Pillsbury was appointed insurance commissioner, by Gov. Stearns, for a period of three years, and has been re-appointed from time to time to the office, which he still holds. Soon after his appointment he drafted and secured the enactment of the present law of the state relative to insurance companies of other states and other countries. This law established the department of insurance, and has given to the people a degree of protection against the frauds and impositions of unreliable companies never before enjoyed is this state, and has brought into its treasury, by tax on insurance premiums, over hundred and twelve thousand dollars, in addition to the compensation of the commissioner.

During the whole term of his office, Mr. Pillsbury has worked quietly but assiduously to eliminate unreliable companies from our borders, and has carefully avoided the admission of all such as are not regarded as perfectly trustworthy. It is universally affirmed by men familiar with the insurance business, that the commissioner of this state has administered his office with unusual skill and success, and his reports are much sought for and often quoted and referred to as authority in other states. The state may well congratulate itself on having had the continued services, for thirteen years, of one so able and experienced in an office so intimately connected with the material interest of the people.

In 1871, Mr. Pillsbury moved to Concord, and the estimation in which he is held in the community is attested by the fact, that, during the eleven years of his residence at the capital, he has twice been elected to represent one of its wards in the legislature, and has been a member of its board of education for seven years, and was president of the board at the time he tendered his resignation. When a member of the legislature, Mr. Pillsbury was eminently practical, and whenever he spoke was listened to with marked attention; for he only addressed the house on subjects that he had thoroughly considered, and it was understood that his remarks were likely to aid the members in reaching a wise and just conclusion.
