=DESCRIPTION OF THE MAPS.=

These maps are made in two forms, both with beautifully executed relief (embossed)—­the cheaper ones of plain stiff paper similar to drawing paper (these are to be substituted for and used as outline map blanks), the others covered with a durable waterproof surface, that can be quickly cleaned with a damp sponge, adapted to receive a succession of markings and cleansings.  Oceans, lakes, and rivers, as well as land, appear in the same color, white, so as to facilitate the use of the map as a =_geographical slate_=.

EXTRA EYES

* * * * *

Have you ever seen the beautiful colors in a fly’s wing? or the hole through a hair, or the little seed babies in the different seeds?  Probably not unless you have some extra eyes to see them with.  We call these EXTRA EYES, MICROSCOPES, Microscope is a name made from two Greek words, MICROS, “small,” and SKOPEIN, “to view,” and is an instrument to look at small things.

A very nice one is shown in the following picture; it has glass plates to put these small things on, a mirror to reflect the light under them, and all of the little instruments necessary.  The price is $2.00, and this covers the entire cost of a nice strong box with a place for each part, which will be sent to any address for this price.
