The Celebrated Original Dust and Pest-Proof 
METAL CABINETS 
FOR SCHMITT BOXES 
These cabinets have a specially constructed groove or trough around the front, lined 
with a material of our own design, which is adjustable to the pressure of the front cover. The 
cover, when in place, is made fast by spring wire locks or clasps, causing a constant pressure on 
the lining in the groove. The cabinets, in addition to being absolutely dust, moth and der- 
mestes proof, are impervious to fire, smoke, water and atmospheric changes. Obviously. 
these cabinets are far superior to any constructed of non-metallic material. 
The interior is made of metal, with upright partition in center. On the sides are metal 
supports to hold 28 boxes. The regular size is 42} in. high, 13 in. deep, 18} in. wide, inside 
dimensions; usually enameled green outside. For details of Dr. Skinner’s construction of this 
cabinet, see Entomological News, Vol. XV, page 177. 
METAL INSECT BOX has all the essential merits of the cabinet, having a groove, 
clasps, etc. Bottom inside lined with cork; the outside enameled any color desired. The reg- 
ular dimensions, outside, are 9 x 13 x 2} in. deep, but can be furnished any size. 
WOOD INSECT BOX.—We do not assert that this wooden box has all the qualities of 
the metal box, especially in regard to safety from smoke, fire, water and dampness, but the 
chemically prepared material fastened to the under edge of the lid makes a box, we think 
superior to any other wood insect box. The bottom is cork lined. Outside varnished. For
