This, plant, which contributes so largely towards the clothing of mankind, and constitutes so important r-a 

 article in the commerce of our country, has not yet been cultivated to any e.xtcnt in this vicinity. I'he 

 summers are generally too short to mature the fruit. But, from some attempts which have been recently 

 made, there is reason to believe that the plant might be gradually acclimated here. Whether it would be 

 advisable for our farmers to turn their attention to an object so much better adapted to the Southern States, 

 'is another question, — which time and circumstances must solve.
