The Cambridge Blue-Book.

The Cambridge blue-book for 1887 will be found to contain considerable information of interest to those who have friends in Cambridge. The book, arranged on the plan of the Boston blue-book, gives the names of the principal streets in Cambridge, and the names of residents on these streets. To anyone endeavoring to make a call in the remote and unknown regions of the city, the references will be of great assistance. In addition to this convenient directory, a list of the buildings and halls, of the fire alarm boxes, railroad stations, etc., is annexed. It might be mentioned in conclusion that the model title of the list of principal disputants is "The Elite-Cambridge Directory."
