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 addi'ion to being abso- 

 lutely dust, moth and dermestes proof, is impervious to fire, smoke, water and atmos- 

 pheric 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 42J in. high, 13 in. deep. 18? 

 in. wide, inside dimensions; usually enameled green outside. For details of Dr. Skin- 

 ner'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 regular dimensions, outside, are 9 x 13x2* in. deep, but can be furnished 

 any size. 



WOOD INSECT BOX. We do not assert that this wooden box has all the quali- 

 ties of the metal box, especially in regard to safety from smoke, fire, water and damp- 

 ness, 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 catalogue and prices inquire of
