THE accompanying cuts illustrate the new electric railway which has been put in at Bangor, Me. One of the cuts shows the car on Main Street Hill, opposite the Opera House, a grade of 7 per cent ; and the other, the car in West Market Square, the very heart of the city. The road at Bangor is three miles in length, single track, with three turnouts, and contains many sharp curves and grades, the most severe of which is a curve of 35 feet radius, which occurs on a grade of 7 per cent. There is one stretch of the road, about

The power-plant consists of one 80-horse-power ThomsonHouston generator, with the necessary station-fittings, which is driven by a 14 by 13 Armington & Sims engine, running at a speed of 250 revolutions per minute. This is the only tramway which has ever been constructed in Bangor, and it has, from the very start, given the utmost satisfaction, but one schedule trip being missed since the day of starting, May 21. The travel has been very heavy, averaging 1,600 passengers per day, and on one day 3,000 were carried by three cars.

In designing these edifices, the idea has been to exhibit the actual dwellings of the masses of the people rather than to represent the palaces of the rich and the powerful; and the rule has also been laid down, to represent the most ancient form, where there has been any great deviation in styles, because the more modern variations are more familiar, and have been more frequently reproduced. Both these limitations, admirable in themselves, have added to the difficulty of the task M. Garnier laid out for himself; for the houses of the rich are more frequently described by ancient writers than those of the poor, and

Gauls, Greeks, and Romans. In 395 A.D. the Roman Empire was divided, and the two parts exhibit distinct features of architectural types. In the West the Roman civilization was overthrown by several invasions, all resulting in distinct architectural types. These were the Huns, the Germans and Franks, and, last in point of date, the Scandinavians. After Europe had passed through the convulsions caused by these inroads, we have the civilizations of the Romanesque period, the middle ages, and the Renaissance. In the East other events were shaping the destinies of humanity. The Roman civilization lasted here some ten centuries ; but it soon lost its earlier characteristics, and developed into the Byzantine. This was further developed in the Byzantine architecture of the Slavs and the Russians, while the Mohammedan invasions of the Arabs and the Turks soon destroyed its distinctive character. All

nier in the “Guide Historique” of M. Ammann, to the exhibition of M. Garnier has divided habitations into two great classes, dwellings. those of prehistoric time, and those of historic. The former period The structures begin with a simple breakwind. Then man found begins with the appearance of man upon the earth, and comes that the shelter of the caves was more durable, and finally a rude down to the time when nations, properly so called, were formed, · hut was attempted. Then begins the long series of artificial and history begins. The historic period includes two subdivis- houses.
