In the Memoirs of the Bath Agricultural Society, the Rev. 

 G. Swayne informs us, that the bush vetch " shoots earlier in the 

 spring than any other plant eaten by cattle ; vegetates late in the 

 autumn, and continues green all winter. But it is difficult to col- 

 lect the seeds, as the pods burst and scatter them about, and, 

 moreover, hardly a third part of them will vegetate, being made the 

 nidus of an insect. A patch sown in drills in a garden was cut five 

 times in the course of the second year, and produced at the rate of 

 twenty-four tons on an acre, of green food ; and when dry would 

 weigh near four tons and a half." The nutritive matter of this 

 ivetch. consists almost entirely of mucilage and sugar ; the bitter 

 extractive principle which exists in the nutritive matter of the 

 Jeaves of all grasses is herein a less proportion. The produce in
