The Boston Journal thinks it useless, after so many years, trying to protect the effort to make sugar in America. Mr. J. J. Gregory, of Marblehead, takes up the Journal, and shows that there has been remarkable progress of late years, and the American Agriculturist gives the following figures in support of this position :

"The fact is well established that some varieties, especially the "Amber" and the "Orange," will yield a large amount of crystallizable cane sugar, and that the cane contains the largest percentage of sugar at the time the seeds are ripe. It is found that after the cane is cut, the cane sugar in the juice rapidly changes to grape sugar, and that the cane should be worked up within a few hours after cutting it. The making of sugar, on account of the expense of machinery and the skilled labor required, cannot be profitably followed by individuals. There needs to be co-operation among farmers to establish and operate sugar works on the same plan that cheese factories are carried on, or they may agree to cultivate a certain number of acres in cane, provided capitalists will establish factories to work it up. In several Western States companies have erected factories and cultivated their own cane on a large scale. These have generally been reported as financially successful."
