The collecting of the plants is first requisite is a tin case or vasculum (), in which the plants are placed, as specimens are pressed when the collectorarrives home. If the vasculum closes tight, the specimens will remain ingood condition for sev-eral hours. If they wilttoo rapidly they maybe lightly sprinkled withwater. Upon journeysor long tramps, a por-table press is sometimesused (shown in ), the pressure beingapplied by means ofstraps. The most im-portant point to be con-sidered in collectingplants is to make surethat the specimen islarge enough and goodenough to fairly repre-sent the plant from which it is taken. A goodspecimen is one which is well pressed and whichcomprises leaves, flowers and fruit; and a com-plete specimen is one which represents every partof the plant, including the Fig. outfit. THE PRESERVING OF PLANTS 441 570. It is important to remember that commonplants are most useful for study, and several speci-mens should be taken, representing different soilsand conditions. If one begins with the thoughtof securing only the rare, curious or beautifulthings, he will probably have an herbarium which isof no particular value. He will have only a col-lection of detached plants. Some theme or mo-tive should run through a collection,—to exhibitthe flora of a neighborhood or a roadside, toillustrate the plants of a forest or a garden, toshow the effects of different environments, andthe like. 570o. In collecting plants, always set out with the ambition tomake good specimens. Collect samples of all parts of the plant,—lower and upper leaves; stem, flowers, fruit, and, wherever practi-cable, roots. In small species, those two feet high or less
