Fortunately, as we observed above, some of the qualities of the cottons which we now cultivate in Italy are excellent, and we ought to base our future cultivation chiefly on these qualities. To incur the hazards and uncertainties of cultivating some new species, when the qualities of the species now in cultivation are good, would certainly not be a prudent course. Now, of the three qualities of cotton at present cultivated, the variety of the Siam cotton possessing a yellow colour is by no means to be recommen-ded. That quality is not souglit after at ali in commerce, nor as it any merit that might cause it to be sought for. Of the two species of white cotton, the Siam species is superior to the other, and it is desirable that it should form the kind of cotton most generally cultivated in Italy. But we should wish, at the same time, that attempts should be made everywhere to grow the herba-ceous cotton, for there may be many localities in which it might be raised more successfully than the other. Experience alone can teach us whether it would be expedient to abandon alto-gether the cultivation of this second species.
   And here I cannot abstain from referring to the cultivation of the long-fibred cotton, kuown under the name of « Sea Island cotton, » because it is the general custom of ali cultivators, when they merely take into account the high price of this cotton, without weighing other considera-
