It would substitute for a mean and shabby portion of the city an ensemble beautiful and effective, and it would bring a large open space to the very edge of a poor tenement section. Owing to the local topography, the proximity of the improvement would not change the character of a large portion of that section; but it would bring civic art almost to the doors of the residents of the neighborhood. My judgment is that the plan does not go far enough. I shall reserve my supplementary suggestion, however, for more appropriate consideration at another point in this paper.

One more comment might be made upon the aesthetic possibilities of the business section before we pass to the tenement district. It is the universal experience of towns that the first streets parallel the water courses. As the business portion of Pittsburgh is located on that tapering point of land where the rivers draw together at an acute angle, it follows that streets must meet at similar angles, and the cross streets multiply them. Very often at these intersections, small triangles are formed, which might have been preserved as open spaces at slight expense before the demand for building room became so great. Although that opportunity has passed, the sharp building lot corners, with the conspicuousness given by a directly approaching street, still offer to architects an opportunity that is rare in American cities. Little advantage is taken of this opportunity. The Wabash Station is one illustration of how much more interesting from an architectural standpoint business Pittsburgh may some day be made.
