Collecting and Preserving Grasses. — Xo person can make 

 satisfactory progress in this study withoiit frequent reference to 

 species with which he has formerly met. For this purpose speci- 

 mens can easil}' be jiressed, poisoned, dried, labelled, classified, 

 and arranged in order, convenient for future reference. A very 

 simple, and in some respects quite desirable method, is to pre- 

 serve the grasses iu the form of dried bunches. In this way they 

 become brittle, and cannot well be handled without damage, but 

 they preserve their appearance, better than those which are sub- 

 mitted to pressure between folds of paper. Even though these 

 dried bunches may not be kept very long, their use is to be 

 recommended. 



If it is within the means of the student, he will find it of 

 great advantage to transplant bunches or grow seed in his garden. 

 In this way he can often see the several kinds and study their 

 peculiarities at every stage of growth. 



On account of scattering seeds which produce young plants 

 that cannot be identified till they have become well established.
