lliiif (lie corrugations run the short way arc used between (lie dryers. When 

 sueculent material is to be dried ir is iicrliaps preferable to use one cor 

 rufiated board between each pair of dryers. For the ordinary type <»f ma- 

 terial two plant sheets with three dryers between each pair of corrugated 

 boards is found entirely satisfactory. fJrasses and other similar plants will 

 be found to dry .satisfactorily when three si)eeiiiiens and four dryers are 

 phiced between the corrugated boards. Folded sheets of newspaper are 

 found to be entirely satisfactor.\ fnv use as plant sheets, though tlie si)eeial 

 sheets for sale by all dealers in hcrliarium supplies are preferred by many 

 collectors. When plants are being dried for illustrative purposes a layer 

 of sheet cotton may be u.sed to advantage between the specimen sheets 

 and the dryers. 



When only a few plants are to be dried and llie press is thin, a floor of 

 loose but closely fitting boards should be laid on each side of the press on 

 the rack so that all the heat will pass through the ccn-rugated boards. For 

 this purpose four boards 38 inches long, two or which are one and a half 

 inches, and two three inches wide should be kept conveniently at hand. 



.Most material will dry in this press in less than twenty-four hours 

 though very succulent plants will require a longer time. If the press is 

 turned over every few lumis during the early part of the drying period

The inside dimensions of the box are IS^^ by 15 inches. The sides are ten 

 inches high, open at the top and bottom. Sockets for electric lights are 

 placed three inches from the buitdni. and the rack on which the press rests 

 is three inches from the top. 



The press is made from one inch boards, 12^2 I'.v IS inches. Canvas 

 straps with friction buckles are pr(i\ ided at either end as illustrated. 



Note the loose boards which are used for a floor at sides of press when 

 only a small quantity of material is being dried. Photo by JI. W. Gardner.
