(3) leaves with three leaflets ; or (4) leaves Digitate with more than 

 three leaflets. 



2. Study the legumes of a farm. Make a list of the forms. 



3. Collect and study the various Clovers to be found in the Ex- 

 perimental g-rounds. In what respect does the young seedling Red Clover 

 dift'er when grown with cereal crops than when grown alone? Is alsike 

 a hybrid, as its scientific name would imply, (Trifolium hyhridum)? 



4. Watch carefully the flowers of white clover {Trifolium repens), 

 and determine how such flowers are fertilized ; what occurs to each flower 

 after fertilization ; how the unfertilized ones (old maids) can be told ? 



5. Which species of clovers are annuals, biennials, perennials? 

 Which are upright growers and which are creeping? 



6. Compare the Medicagos with the Clovers. Is Black Medick a 

 weed ? 



7. Compare the Melilots with the Clovers. Is White Mejilot a 

 weed ? 



8. Contrast the Peas and the Vetches. Compare their flowers, and 

 note any points of difference between them. What difference in ger- 

 mination? Make drawings. 



9. Collect and preserve the tubercles of the various legumes. 



XXII. Grass Investigations. 



1. Collect samples and bundles of the various wild and cultivated 

 Grasses. 



2. Determine the following regarding each Grass : 

 {a) The time of Flowering. 



(6) The height of growth. 



(c) How it withstands drouth. 



(d) How it withstands excess of water, 



(e) How it withstands pasturing. 

 (/) Its palatability. 



(.£r) Its roots, habits, whether creeping, or tufted. 



(h) Its duration, whether annual, biennial, or perennial. 



3. Make germination experiments of as many grasses as possible, 

 and study the habits of the seedlings. 



4. Collect samples of commercial grass-seed from various seed 

 houses, and determine the purity and vitality. 



XXIII. Recognition of Grasses by tlieir Leaves. 



1. Ascertain how the leaves are folded In the bud, whether (a) 

 simply folded, or (b) rolled. Poa pratensis (June Grass) is folded, and
