As tbe plants lose moisture the rtqies will require to be .tightened; before doing this It is advisable to undo tbem and look over the specimens to tee that all tbe parts are pror«rly displayed; leaves are liable to accidentally overlap or double up. It may oocasloDally be necessary to remove damp sheets and replace by dry ones. As a rule, however, this is unnecessary, so that the work of plant-pressing is reduced to a minlmnui, and tbe monotony of repeatedly changing the papers ia practically dispensed with. t'ndfr ordinary conditions drying will be completed In from one to three days, according to tbe nature and number of spedmens in tbe bundle. They should not, however, be removed from the presser until quite dry (this is usually ascertained by their becoming more or less brittle), otherwise l>eatttlful qieclmens may slirlvel and become useless.
