Parts or wholes of green plants should be dried under 

 rath?> heavy pressure between frequently-changed, warm, dry, 

 drying-papers, and attached to the page with very narrow 

 strips of tough gummed paper. 



Small specimens, such as seeds or detached parts, are usually 

 placed in pockets, to be pinned or 

 gummed to the page. The standard 

 specimen-pocket is made of an oblong 

 of paper of suitable size— say, for 

 example, 5 x 3J inches. Fold it

Collections of Seeds. — There is danger of mistaking the mere 

 making of collections for real Nature Study. (See p. 28). 

 Collecting specimens has, however, certain incidental values. 

 It exercises discrimination, leads to classification, and takes 

 people afield. Manual dexterity and artistic taste are required 

 in the proper arrangement and mounting of some kinds of 

 objects. 1 All these are desirable results, but from the Nature 

 Study point of view they are more than counterbalanced if 

 the collecting becomes an end in itself or involves destruction
