A full car-load is reckoned at seven tons. It has been found in the operation of railroads that an engine which will move one hundred and seventeen tons on a grade sixty feet per mile will move only about fifty tons on a grade of one hundred and sixteen feet. A second glance at the diagram (p. 48) shows us that the sum of ascents and descents on the line already constructed must be vastly greater than that now under construction; and inasmuch as it is impossible to carry a load up or down hill without costing something, it follows that this road can be operated more economically than a line crossing four mountain-ranges, and the ultimate result will be a cheapening of transportation across the continent, and a great development of the Asiatic trade. Throughout the entire distance between Lake Superior and the Pacific Ocean along the line, the husbandman may turn the sod with his plough, the herdsman fatten his flocks, the lumberman reap the harvest of the forests, or the miner gather golden ore. A Bureau of Emigration is to be established by the company, which will be of invaluable service to the emigrant. Many persons in the Eastern and Middle States are desirous of moving to the Northwest, but it is hard to cut loose from old associations, to leave home and friends and strike out alone upon the prairie; they want company. The human race is gregarious. There are not many who care to be hermits, and most of us prefer society to solitude. This feature of human nature is to be kept in view, and it will be the aim of the Bureau of Emigration to offer every facility to those seeking new homes to take their friends with them. Upon the completion of every twenty-five miles of road, the company will be put in possession of forty sections of land per mile. The government will hold the even-numbered sections, and the company those bearing the odd numbers. The land will be surveyed, plotted, and the distinctive features of each section described. Emigration offices are to be established in our own country as well as abroad, where maps, plans, and specifications will be found. One great drawback to the settlement of the prairie lands of Illinois and Iowa has been the want of timber for the construction of houses. Persons with limited means, having only their own hands, found it hard to get started on a treeless prairie. Their first work is to obtain a house. The Bureau propose to help the man who is anxious to help himself on in the world, by putting up a portable house for him on the land that he may select. The houses will be small, but they will serve till the settler can get his farm fenced in, his ground ploughed, and two or three crops of wheat to market. The abundance of timber in Minnesota will enable the company to carry out this new feature of emigration.
