Obs Tnis plant, so higiily and justly esteemed by our Agriculturists, has become completely naturali- 

 zed The culture oi it began to prevail, here, about 35 years ago; and it is now sedulously pursued by ev- 

 ery good farmer. It ameliorates the soil, affords good pasture, and, when mixed with Timothy, Orchard- 

 g-r'ijis, caJ some of the other culmiferous plants, makes first-rate hay. The mtroduction of clover, with 

 the us.- of gypsum, has put an entirely new face upon this district of country, within the period above men- 

 tione J. Tae seed is usually sown in the month of March, among green wheat, and rye; and it has been re- 

 nii:-ked tl.at It generally succeeds best among the latter. It is the seccmrf growth, or crop, of the clover, 

 froff. whit'h ihe seed is obtained, for sowing; and it is ripe in the beginning ot September. The universal 

 prevalence of this plant, here, has been sadly unprophious to the labors of the Honey J5ec,— inasmuch as the 

 tube of the corolla is so long that the little insect is not able to reach the nectar with its proboscis.
