other cases it will be found best to take up these topics after the 

 consideration of the great groups: 



Relation of plants to light, soil, water, atmosphere, gravity, 

 contact, seasons. 



Growth and reproduction. 



Responses of different regions. 



Artificial control and methods of improving agricultural and 

 horticultural plants. 



Forests, their uses, distribution, dangers, and preservation. 



The study of types differs little in range from the recommenda- 

 tion of the Botanical Society. In the cryptogams field work is 

 more definitely recommended ; the species selected in each group 

 are in most cases left to the teacher, but the life, habits, and dis- 

 tribution are included with the life cycle requirement. Bacteria 

 in relation to crops, sanitation, and disease occupy a much more 

 prominent part. The suggestions for gymnosperms and angio- 

 sperms are reprinted below: 



1. Gymnosperms. Pine or spruce as a type; habit of tree, per- 

 ennial nature, twigs and stems of different ages, age of tree, leaves 

 and the evergreen habit, nature of the timber and its uses; two 

 kinds of cones and the processes, time and structures involved 

 in seed formation, nature of the seed, seed distribution, seedlings 

 and the establishment of the new tree. 



Names of other kinds of gymnosperms. 



Gymnosperms as source of much of the world's lumber supply, 

 chief regions of gymnosperm forests, preservation and extension 

 of gymnosperm forests. 



2. Angiosperms. 



Life cycle as compared with the gymnosperms. 



Types of stem, root, leaf and flower structure, with considera- 

 tion of the special work, habits, and uses of each of these. 



Nutritive and reproductive processes arranged so as to extend 

 whatever work was done with seed plants at the beginning of 

 the course. Work suggested at the outset that was not done in 

 that connection may be included here. 



Pollination and seed formation, number of seeds, seed distribu- 

 tion, seedlings, vitality of seeds, struggle for existence.
