On Sunday evening I attended a service at Trinity Church, having been attracted by the exterior of the building, which is a conspicuous object from some points in Michigan Avenue. I mention this because I observed a peculiarity in the means used for lighting it, which might occasionally be adopted with advantage in London, and large cities where sites are costly. I suppose the space was so confined by dwelling houses on the north and south sides, that windows in the walls of the aisles were inadmissible. This difficulty had been met boldly by enlarging the clerestory windows, and adding in the roof rows of quatrefoil skylights, filled with very dark stained glass. I should have been glad to have seen the effect of this by daylight. Nine tenths of the congregation I saw in this church that evening were gentlemen, from which I inferred that the service was intended mainly for the rougher sex. What is conventionally regarded by us as the American type of features is not uncommon on the Eastern seaboard, but is seldom seen in the West. The clergyman whom I saw officiating in Trinity Church might have sat for the bust of a Greek philosopher. He had a massive head, with much refinement about it; a lofty forehead, a straight nose, and a magnificent beard. He spoke in a manly and soldierly way of what he had witnessed on the battle-fields of the late war. A new and completely distinct type of features has been developed in America. Of all races of men, that from which the Americans are descended has the greatest mixture and variety of features. We have no facial type. We have round heads and long heads; low, high, prominent, and receding foreheads; large jaws and small; our noses are infinite in multiformity; we have long and short, thick and fine, pug, Roman, and straight, each in all degrees. In America, however, the whole of this variety has been lost and obliterated. The descendants of the most various-featured race of mankind have become one of the most uniform-featured race in the world. Whatever part of the country you may be in, you will find the same thing. As a general rule, the native Americans all have straight noses off straight foreheads, and small jaws. Their faces have been brought to one type, and that a far more intellectual one than what we are familiar with in the old country: it is almost the antipodes of that to which the conventional John Bull belongs. To be convinced of this, it is only necessary to look at the features of the passengers in a railway car, or at the Americans one meets in private houses, or at places of public amusement. The straight nose and forehead are everywhere the rule. I saw at Richmond a frame containing the photographs of the fifty Southerners who had most distinguished themselves in the late war. There was not a single pug, or short or Roman nose among them. It has been just the same with the Greeks; whatever race of people has inhabited the soil of Greece, has assumed the Greek type of feature.
