As the homestead privilege must largely increase immigration, and add especially to the cultivation of our soil, it will contribute vastly to increase our population, wealth, and power, and augment our revenues from duties and taxes. As this domain is extended over fifteen States and all the Territories, the completion of these enlarged canals, embracing so large a portion of them, would be most advantageous to all, and the inducement to immigration would greatly increase, and immigration must soon flow in from Europe in an augmented volume. Indeed, when these facts are generally known in Europe, the desire of small renters, and of the working classes, to own a farm, and cultivate their own lands here, must bring thousands to our shores, even during the war. But it will be mainly when the rebellion shall have been crushed, the power of the Government vindicated, its authority fully reestablished, and slavery extinguished, so as to make labor honorable everywhere throughout our country, and freedom universal, that this immigration will surge upon our shores. When we shall have maintained the Union unbroken against foreign and domestic enemies, and proved that a republic is as powerful in war as it is benign in peace, and especially that the _people_ will rush to the ranks to crush even the most gigantic rebellion, and that they will not only bear arms, but taxes, for such a purpose, the prophets of evil, who have so often proclaimed our Government an _organised anarchy_, will lose their power to delude the people of Europe. And when that people learn the truth, and the vast privileges offered them by the Homestead Bill, there will be an exodus from Europe to our country, unprecedented since the discovery of America. The wounds inflicted by the war will then soon be healed, and European immigrants, cultivating here their own farms, and truly loyal to this free and paternal Government, from which they will have received this precious gift of a farm for each, will take the place of the rebels, who shall have fled the country. We have seen that the total cost of our railroads and canals, up to this date, was $1,335,285,569, and I have estimated the probable cost of these enlarged works as not exceeding one tenth of this sum, or $133,528,556. Let us now examine that question. We have seen that our 4,650 miles of canals cost $132,000,000, being $28,387 per mile, or less, by $8,395 per mile, than our railroads. It will be recollected that a large number of miles of these canals have already the requisite depth of seven feet, and width of seventy, and need only an enlargement of their locks. It appears, however, by the returns, that the Erie canal, the Grand Junction, Champlain canal, and the Black River, Chemung, Chenango, and Oswego, in all 528 miles, are all seven feet deep, and seventy feet wide, and cost $83,494 per mile, while the average cost of _all_ our canals, varying from forty to seventy-five
