EXPERIMENTS "WITH WEEDS. 



The piece of ground, II by 33 feet, called "the weed belt," has 

 been continued for the fifth seaeon. Plants have grown wild, ripened! 

 their seeds and scattered them as in a wild state. The following is 

 the list of fourteen species most prominent during the year : 



1. Ruinex aceloseUa L. (0), (7), (4), (1). 



2. Bromus racemosus L. 



3. Abutilon Abutilon L. (7), (2), (6). 



4. Polygonum Pennsylvanicum L. (6), (3), (2). 



5. Daucus Carota L. (12), (0), (0), (4). 



6. Chrysanthemum Leucanihemum L. (0), (0), (0), (9). 



7. Silene noelijlora L. (9), (13), (14), (7). 



8. Taraxacum Taraxacum L. (0), (0), (9), (5). 



9. Convolvulus arvensis L. 



10. Melilotm alba L. (0), (0), (0), (12). 



11. Oxalis stricta L. (0), (0), (0), (8). 



12. Plantago lanceolata L. (0), (0), (11), (10). 



13. Radbeckia hirta L. 



14. Ambrosia artemiscefoUa L. (3), (5), (1), (1). 



It is seen that there are three new species upon the list, an d of the 

 eleven old ones many have changed places. A brome-grass, the fiel(^ 

 bindweed and yellow daisy are the ones that have come toward the 

 front, while the ragweed, for example, has dropped from the head 

 to the foot of the list. The smartweed', velvet leaf, wild carrot andli 

 catchfly are all near their places for 1900. 



There are many competitors not in the above list, among which the 

 following are mentioned : 



Three kinds of clover — white, alsike and red ; five kinds of grasses 

 — timothy, foxtail, redtop, a poa and a fescue ; dock, mercury, 

 goose-foot, four asters, burdock, flea bane, salsify both cultivated 

 and wild, broad plantain, asparagus, tomato, young grape vine and 

 small cherry tree. 



One of the things observed is the tendency for the ground to become 

 covered with a growth of low plants, 'as the clovers and grasses and 

 bindweed ; along with this there is a formation of a second layer of 

 foliage, represented by the sweet clover, yellow daisy, velvet leaf and 

 smartweed. Above this will be the cherry tree and the grape vinCy 

 providing the latter reaches the tree, as it is very likely to do in time
