THE YOUNG SCIENTIST. 
A Cheap Cabinet for Wooden Slides. 
IT is the object of this cabinet to do away 
with the " elastic band " arrangement, 
and its inconveniences, and to afford a 
receptacle for uncovered wooden slides 
which shall at once exclude all dust from 
the objects, admit of quick reference, and 
be cheap and easy of construction. 
The slides lie flat as at o, and the objects 
in each compartment may be indexed by 
labels pasted on (h h). If the compart- 
ments are kept filled with slides (both 
with and without objects) when the cabinet 
is shut up, the rubber springs (r r) press- 
ing on the slides will squeeze them to- 
gether, and so exclude all dust. 
A very neat appearance is given to the 
A CHEAP CABINET EOK WOODEN SLIDES. 
It consists of a segar box of convenient 
size, with front (f) and cover (c) hinged. 
A cloth hinge answers every purpose. 
The interior is divided into compart- 
ments 3 1-16 X 1 1-6 in, by several parti- 
tions, (p p p p p) which are held in place 
by a piece of wood (h h), fastened in the 
back of the box and having sawed in it 
several slots into which the several parti- 
tions are glued. 
On the cover are attached disks of rub- 
ber (r r) (made by cutting small rubber 
stoppers into four parts) or rubber rings 
(made from tubing)— the latter being put 
on upright. There should be two to each 
compartment; the upper or front ones 
about I inch from the front edge, and the 
lower, or back ones, about Is in. from 
them. "When the box is closed, the front 
(r) is kept in place by an overlapping piece 
of metal, (b) screwed on to the top, and the 
cover is pressed down by means of two 
stout wire catches (l l).
