On Boston's commercial greatness there is no space to touch. Nor is it needed. Could her schools, her churches, her charities, her institutions, public and private, which have here been outlined, flourish without the backbone of Puritan thrift and the framework of prosperity which have made her one of the wealthiest of cities? The solid business foundation is apparent to all who visit her teeming marts and exchanges. But the "power behind the throne" is kept with rare judgment in the background; and when the visitor comes to kiss the hand of the "Queen of the Commonwealth" he sees only her chosen handmaids--Ambition, Culture, Philanthropy, Religion. On these, finally, she rests her claims to greatness. CHAPTER III. LECTURE AT TREMONT TEMPLE. Lecturing in the towns I purposed visiting was an after consideration of secondary importance--a sort of adjunct to the journey and the objects I had in view. It was thought that it might afford some facilities for meeting large numbers of people face to face in the different sections of the country through which I designed to pass, and thus enable me the better to learn something of their social customs, industries and general progress in the arts of civilization. The subject decided upon for the lecture was "Echoes from the Revolution," and was intended to be in keeping with the spirit of the Centennial year. The fact that I had been a cavalryman during the War of the Rebellion and the novelty of an equestrian journey of such magnitude would, I estimated, very naturally awaken considerable interest and a desire on the part of many to hear what I had to say of the heroes of "76." My lecture was a retrospective view of the leading incidents of the Revolution, with especial reference to some of the sturdy heroes and stirring scenes of that most eventful period in American History. Briefly referring to the causes which led up to the war, I started with the Ride of Paul Revere from Boston the night before the Battle of Lexington, and closed with the Surrender of Cornwallis at Yorktown. It was not my wish or intention to derive any pecuniary benefit from my lectures; but being a member of the Grand Army of the Republic, and thoroughly in sympathy with the aims and benevolent projects of my soldier friends, it was proposed to donate the proceeds to the Relief Fund of that patriotic organization. Fully equipped, the weather favorable and roads in good condition, I was anxious to begin my journey early in May. It was therefore arranged, as previously suggested, that I should lecture at Tremont Temple on the evening of May eighth under the auspices and for the benefit of the G. A. R. Relief Fund. The subjoined fraternal and highly complimentary letter of introduction from Captain Frank M. Clark of New York was received by the committee of arrangements soon after my arrival in Boston.
