Prosperity Of Cuba

vaneing in population und all other ources of wealth. It is ealeulated that the present population of the Island is 1,168,000, of which nearly 550,000 are white inhabftants, 180.000 free culored, 400,000 slaves, and 38,000 Aeiatics and lndians. The sugar estafes are immensely productive. - Twenty-threa of the principal plantations, cornprising about 1.100,000 acres of land and 10,175 slaves, besides buildings, raar.hinerv, &c, ars valued at nearly 815,000,000. The Cuban Mettengcr saye: Tbe total amount (last year's erop) of sugar from these 23 estatus, was 835,000 boxes, which, calculuted at the pnces of last year, can be estimated at $20 each box would makethe value of their aggregate crops $4,700,000 or over 30 per cent, more than the estimated value of property. The expenses of manufacturing, keeping the hands, fucl, &c, must be deduc'cd from that surn to see the real profita, wbib according to many planters rurely net 10 per cent. We merely give these iew items for the gratification of some parties interested in the sugar business; and as there are over sixteen hundred sngar planlations in the Island, it will be easily unclerstood that the value of our principal staple must be great, indeed, ■hen the total exports of this singla article (sugar) from the ports of Havana and Mantanzas alone, have exceetled, during the years of 1858 and 1851), over 1,200,000 boxes. When we ean phow the total production of the Island, it will be been that the value of the tugar-cane production alone has been over $50,000,000 per annum lor several yeara. - 

 A letter from Chicago to the Albany Argus says: "I have just had a long conversation with an intelligent gentleman from Kentucky, who has been traveling on business through Ohio, Indiana, Illinois anti Missouri, and he asserts thatjust as certainly as tbe dny of election shall asrive, just so certainly will Mr. earry all these States, and Illinoia by not less tban 20,000 majority. And so strongly is the courso of public sentiment setting in favor of Douglas in thesouthern States, that ho confidently anticipates that scarcely a Breckinridgo ticket will be run thero in November. The people of the South, he says, are with Douglas. Again, I met a domocrat from Wis(;on8in, who said: ' I know much about Wisconsin, having been all over tho State, and, knowing the sentiments of the masses, I assure you WisconfMTi will, beyond all question voi for Douglas, and by a uecisive vote.'"
