The two hundred and twenty-fifth anniversary of the settlement of Dorchester was celebrated on the 4th of July, 1855. The oration was by Edward Everett; Mr. Wilder presided and delivered an able address. On the central tablet of the great pavilion was this inscription: "Marshall P. Wilder, President of the Day. Blessed is he that turneth the waste places into a garden, and maketh the wilderness to blossom as a rose."

In January, 1868, he was solicited to take the office of president of the New England Historic-Genealogical Society, vacated by the death of Gov. Andrew. He was unanimously elected, and is now serving the fourteenth year of his presidency. At every annual meeting he has delivered an appropriate address. In his first address he urged the importance of procuring a suitable building for the society. In 1870, he said: "The time has now arrived when absolute necessity, public sentiment, and personal obligations demand that this work be done and done quickly." Feeling himself pledged by this address, he, as chairman of the committee then appointed, devoted three months entirely to the object of soliciting funds, during which time more than forty thousand dollars was generously contributed by friends of the association; and thus the handsome edifice. No. 18 Somerset street, was procured. This building was dedicated to the use of the society, March 18, 1871. He has since obtained donations amounting to upwards of twelve thousand dollars, as a fund for paying the salary of the librarian.

In 1859, he presided at the first public meeting called in Boston in regard to the collocation of institutions on the Back Bay lands, where the splendid edifices of the Boston Society of Natural History and the Massachusetts Institute of Technology now stand. Of the latter institution he has been a vice-president, and the chairman of its Society of Arts.

He was one of the twelve representative men appointed to receive the Prince of Wales in 1860, at the banquet given him in Boston; also one of the commissioners in behalf of the Universal Exposition in Paris, 1867, when he was placed at the head of the committee on horticulture and the cultivation and products of the vine, the report of which was published by act of congress.

In 1869, he made a trip to the South for the purpose of examining its resources; and in 1870, with a large party, he visited California. The result of Mr. Wilder's observations have been given to the public in a lecture before the Massachusetts state board of agriculture, which was repeated before the Boston Mercantile Library Association, the Amherst and the Massachusetts Agricultural colleges, Dartmouth College, the Horticultural Society, and the merchants of Philadelphia, and bodies in other places.

His published speeches and writings now amount to over eighty in number. A list to the year 1873 is printed in the "Cyclopedia of American Literature." Dartmouth College, as a testimonial to his services in science and literature, conferred upon him, in the year 1877, the degree of Doctor of Philosophy.

The Hon. Paul A. Chadbourne, LL. D., late president of Williams College, in a recent memoir of Mr. Wilder remarks: "The interest which Col. Wilder has always manifested in the progress of education, as well as the value and felicitous style of his numerous writings, would lead one to infer at once that his varied knowledge and culture are the results of college education. But he is only another illustrious example of the men who, with only small indebtedness to schools, have proved to the world that real men can make themselves known as such without the aid of the college, as we have abundantly learned that the college can never make a man of one who has not in him the elements of noble manhood before he enters its halls."

In 1820, Mr. Wilder married Miss Tryphosa Jewett, daughter of Dr. Stephen Jewett, of Rindge, a lady of great personal attractions. She died on a visit to that town, July 21, 1831, leaving four children. On the 29th of August, 1833, Mr. Wilder was united to Miss Abigail, daughter of Capt. David Baker, of Franklin, Mass., a lady of education, accomplishments, and piety, who died of consumption April 4, 1854, leaving five children. He was married a third time on the 8th of September, 1855, to her sister, Miss Julia Baker, who was admirably qualified to console him and make his dwelling cheerful, and who has two sons, both living. No man has been more blessed in domestic life. We know not where there would be a more pleasing picture of peace and contentment exhibited than is found in this happy family. In all his pursuits and avocations, Mr. Wilder seems to have realized and practiced that grand principle which has such a bearing and influence on the whole course of life,—the philosophy of habit, a power almost omnipotent for good or evil. His leisure hours he devotes to his pen, which already has filled several large volumes with descriptions and delineations of fruits and flowers proved under his own inspection.

The life of Col. Wilder is a striking instance of what an individual may accomplish by industry, indomitable perseverance, and the concentration of the intellectual powers on grand objects. Without these, no talent, no mere good fortune could have placed him in the high position he has attained as a public benefactor. He has been pre-eminent in the establishment and development of institutions. Few gentlemen have been called upon so often, and upon such various occasions, to take the chair at public meetings or preside over constituted societies. Few have acquitted themselves so happily, whether dignity of presence, amenity of address, fluency of speech, or dispatch of business be taken into consideration. As a presiding officer he seems "to the manner born." His personal influence has been able to magnetize a half-dying body into new and active life. This strong personal characteristic is especially remarked among his friends. No one can approach him in doubt, in despondency, or in embarrassment, and leave him without a higher hope, a stronger courage and a manlier faith in himself. The energy which has impelled him to labor still exists.

In closing this sketch, we may remark that a complimentary banquet was given him, September 22, 1878, on the eightieth anniversary of his birth. On this occasion the Rev. James H. Means, D. D., his pastor for nearly thirty years, the Hon. Charles L. Flint, secretary of the board of agriculture, the Hon. John Phelps Putnam, judge of the Massachusetts superior court, and others paid tributes to the high moral character, the benevolent disposition, and the eminent services of the honored guest of the evening.
