' fruits, cones, wood sections, etc., still keeping up a desired uni- 
form outside appearance. 
In the permanent herbarium, these cases can be snugly piled 
one on the other, in tiers three or four in height, and closely 
fitting at the sides. The lower cases might be raised a foot or 
more above the floor, or the least used orders, or duplicates, kept 
in the lowest space. 
The height of two cases (39 inches) would be convenient in 
looking over and comparing specimens, and where scarcity of 
case room is not urgent, the best lighted spaces might be arranged 
at this height. 
At a rough estimate such cases may be calculated to hold 
conveniently six hundred species of average botanical specimens. 
The cost of such cases, depending of course, largely on the 
material used, and amount of finish, etc., has been fixed by a 
manufacturing firm here in Davenport, Iowa (M. B. Cochran & 
Co., school furniture dealers), at $6.50 per case. For a larger 
number (ten or more), or in case of an increased demand, the 
price could be materially reduced. I am indebted to the above 
firm for the use of the wood-cut, here given to illustrate this sub- 
Ject. The particular adaptation of such cases for school u 
to contain in convenient form the necessary material for illus- 
trating botanical lessons, is too obvious to require more than 
simple mention at this time.
