New School Projection Lantern C
This lantern has been designed with special reference to school work, the aim being to produce an apparatus of per- fect mechanical construction and the latest improvements (feat- ures that have heretofore been embodied in the higher priced lanterns only) at a moderate price.
This device is simple, efficient, portable and convertible, and can be used either single, or double with a dissolve!. Made for use with arc light or acetylene gas. It can be equipped with microscope and thus practically covers the whole range of school projection work. Price complete as shown $50. With acetylene burner $45.

AUBURNDALE, MASS.
The purpose of Lasell is to develop its pupils into a high type of womanhood.
A sound body, well-trained mind, and a character with high ideals, are the logical result of the home-school life at Lasell. Many parents have written strong commendatory letters on the unusual quality of the schoolwork.
Beautiful, healthful location ten miles from Boston. Special advantages in Music, Art and Home Economics.
Lasell is well worth investigating.
