We have strayed far from our text--from our long ago early visit to Boston. Our first impression of the town then came from a policeman whom we saw in the old Kneeland street station. The policeman had white side-whiskers and he wore gold-bowed spectacles. We have never, either before or after our first arrival in Boston, seen a policeman adorned, either simultaneously or separately, with white "mutton-chops" or gold-bowed spectacles, and so it was that this Bostonian made a distinct impression. Boston, itself, made many impressions. Twenty years ago many of the institutions of the town that have since disappeared, still remained. True it is that the horse-cars were going from Tremont street, for the first of the diminutive subways that have kept the city years ahead of most American towns in the solution of her intra-urban transportation problems had been completed and was a nine-days' marvel to the land. The coldly gray "Christian Science Cathedral," with its wonderful Sunday congregations, could hardly have existed then, even as a dream in the mind of its founder. And the Boston Museum still existed. To be sure, many of its glories in the days of William Warren and Annie Clarke had disappeared and it was doomed a few months later to such attractions as the booking syndicates might allot it, but its row of exterior lamps still blazed in Tremont street: until in June, 1903, it rang down its green baize curtains and closed its historic doors for the last time. And yet Boston has not changed greatly in twenty years--not in outward appearance at least. When she builds anew she builds with reverent regard for her ideals and her past traditions. Her architects must be steeped in both. Nearly twenty years ago she builded her first skyscraper--a modest and dignified affair of but twelve stories--and was then so shocked at her own audacity that she promised to be very, very good for ever after and never to do anything of that sort again. So when she found that a new hotel going up near Copley Square had overstepped her modest limit of seven stories--or is it eight?--she showed that she could have firmness in her determination. She chopped the cornice and the upper story boldly off the new hotel, and so it stands today, as if someone had passed a giant slicing-knife cleanly over the structure.
