There are four buildings in the process of construction at Princeton, the art museum, magnetic observatory, the dynamo house and Brown hall. The latter is a dormitory 175 feet long, the gift of Mrs. S. D. Brown of Trenton...
...more powerful machines are called "Series machines," in which the current from the dynamo is strengthened by passing through all the large coil of its electric-magnet. The ordinary are light is made by breaking the outside circuit of a Series machine. The carbon tips must be together when the current is started, and the break is made by lifting the upper one a little by a mechanical arrangement. The powerful current, in overcoming the resistance offered by the air, heats the carbon tips to a white heat. In the incandescent lamp the resistance is offered by a filament...
...plans of the Edison Company have been approved by the corporation, and the main trouble just now is as to where the dynamo can be placed with most advantage. It is necessary to avoid the noise which it would make, were it placed in the cellar of Gore Hall, and the expense of laying the wires will be increased by just so much for every yard the dynamo is distant from the building it is intended to supply. But this is a question which it will take but a very few days to settle...
...dynamos are also considerably modified, thought the differences are not evident to the untrained eye, as in the case of the lamps. The inventor claims for these dynamos a capacity of fifteen or more lamps per horse power against eight or ten by all other systems. But the great interest to the public at large, and to Harvard students in particular, lies in the fact that these new machines can be constructed so cheaply as to be no more expensive than gas, so that there is no reason why we should not all have the electric lights in our rooms...
...would give a better light, less heat, no smell and no care. The Edison system of incandescent lights with the pretty and inexpensive electro-liers such as are in use in the Bijou Theatre would be just what is needed. The electricity needed could be furnished by the dynamo-electric machine in Boylston Hall which is under the charge of the assistants .This would necessitate only a short line of wires from one building to the others. To defray the expenses, which would be slight after the plant was put in, the college could certainly find the means. For supplying...
