While our figures and illustrations in regard to the opening of a farm, and the expenses attending thereon, have been as explicit and full as our space would permit, still we regard them but as a basis for a variety of similar calculations to be made by intending immigrants. For instance, two friends might buy a breaking team between them, and break, say twenty acres, on each one's farm. One could do the breaking, while the other might be doing some other work. In fact, each man's case has its own peculiar features, which he must bring his own judgment to bear upon, and we don't pretend to have done more than to have given him a good guide to assist him in his calculations. Twenty acres would be a pretty fair breaking for a poor man the first year, and quite sufficient to enable him to support a small family. We have farmers in the woods, now prosperous men, who for years had not more than from five to ten acres cleared, for it is hard work to clear heavy timbered land, and much easier to plant young trees than to cut old ones down. But heretofore poor men were frequently deterred from going on prairie land on account of the heavy expense attached to fencing their tillage land. This was about the highest item of expense. It is not so now, for in the counties in which our Catholic colonies are situated, and in the adjoining counties, A HERD LAW is in force, whereby cattle have to be herded during the day, and confined within bounds during the night. In this way one man or boy can herd the cattle of a whole settlement, and the heavy, vexatious and continual tax of fencing is entirely done away with. All the lands in our Catholic colonies are prairie lands, and in the colonies and adjoining counties, as we have already stated, the herd law is in full force. No one, at the present day, who has any experience in farming in the West, would settle on an unimproved timber farm. It takes a lifetime to clear such a farm, and even then a man leaves some stumps for his grandchildren to take out. But we earnestly impress upon our settlers the necessity of setting out trees around their prairie homes. The rapid growth of trees set out on any of our prairies, is absolutely wonderful. In six years after planting, a man will have nice, sheltering, young groves, around his house. One of the first things a settler should do after breaking up his land is to set out some young trees, which he can buy very cheap. All our railroads carry such freight free. If he cannot get the trees he can sow the seed, which will do as well. For comfort on a prairie, trees are a necessity; but it is worse than useless, it is loss of time, to set them out, unless they are taken care of: give them solitude, and keep the weeds and cattle from them for a little while, and they will soon be able to take care of themselves. Cord-wood can be bought at any of the railroad stations in our colonies at an average of about five dollars a cord.
