Excerpt from Collecting Data and Specimens for Study of Economic Plants Only rarely can a satisfactory answer be given to inquiries about some native plant when nothing more is known than its local or vernacular name. A native name for a plant in a foreign country may not have any more significance than would a common name in the United States. A plant called brown daisy in one State may well be known as blue eyed marigold in another. In Latin American countries, also, the common name Of a plant Often varies from one locality to another. For this reason, the local name is not a sufficient clue to the botanical iden tity Of a plant. Likewise, people Often send in a single leaf, a piece Of stem, or a root only to learn that small fragments are inadequate. Bota nists need a sufficient portion Of a plant, with flowers or fruits, some times both, -in order to identify it and to assign the correct botanical name. The specimen must be pressed flat and dried before shipping. Fresh plants wrapped in Oilpaper for mailing usually arrive completely decayed. A plant tucked into an envelope arrives in a shriveled condi tion or else shattered to bits. The best method Of assuring safe shipment is to protect the dried specimen with two pieces Of stout cardboard. Insect and diseased-plant specimens, as well as analysis and propaga tion material, also must be adequate in quantity, properly prepared, and carefully packed. Fungi and insects should never be shipped from one country to another while still. Alive, unless specifically requested by specialists; and in that event special arrangements would need to be made to conform with the quarantine laws Of the countries concerned.

Excerpt from Collecting and Preparing Study Specimens of Vertebrates Head each notebook page with collector's name and year, page number (if number system is used), locality (in detail the first time used), and date. Write full notes, even at risk of entering much information of seemingly little value. One cannot anticipate the needs of the future, when notes and collections are worked up. The following are suggested topics, but do not restrict yourself to these alone. Be alert for new ideas and new facts. Describe vegetation (saving plant-press samples of Species not positively known), nature of ground, Slope exposure, and drainage in each belt of animal life sampled. Describe exact location of trap lines, referring to your topo graphic maps, and also enter a sketch, in profile or surface view or both, to illustrate the location and relations of the different habitats crossed. Properly marked maps for each region worked Should ultimately be bound in with the field notes of at least one member of your field party. Keep full record of breeding data: number and approximate Size (length) of embryos or of young found in nests. Dig out burrows if practicable; make drawings to scale, showing plan, and elevation; describe fully. Record food plants; keep Specimens for identification where not known by a definite name; preserve contents of cheek pouches and stomachs. If these are not saved, identify and record contents. Note regularly in notebook all pick-ups, that is, odd skulls or fragments of animals of whatever sort or source, serially numbered along with specimens of the more usual sort. Give full information, as with odd skulls secured from trappers. Label all such specimens adequately, as elsewhere described. When leaving a well-worked locality, enter in the journal section of your field notes a summary of Species observed, with remarks of a general nature, relating to local conditions of terrain, human activities, and other pertinent conditions.

Excerpt from Biological Atlas: A Guide to the Practical Study of Plants and Animals The attempt to encourage practical work in Biology by means of clear figures briefly explained, and accompanied by instructions for the examination of specimens, has evidently been received with favour, since a second edition of the Biological Atlas has been called for within a year of publication. Both Text and Plates have been carefully revised, and such alterations and improvements made as will tend to render it still more serviceable. However, few changes have been found necessary.
