Next, we will suppose one wishes to plant walnuts where they can not be had from the woods, but must be shipped in. There seems to be only one plan by which this can be done safely every time, which is as follows: Gather the nuts as they fall from the trees--of course when they begin to fall naturally all may be shaken down at once--and spread them not over a foot deep, on the bare ground under the shade of trees. Cover out of sight with straw or leaves, with some sticks to hold in place called a "rot heap;" then after they are frozen and will stay so, they may be shipped in bags, boxes, barrels, or in bulk by the car-load, and then, again, placed in "rot heaps," as above, until so early in the spring as the soil is in workable condition. Then plant as directed in the fall, except the soil should be firmly packed around the nuts. Keep free from weeds by good cultivation, and in due time you will have a splendid grove. There was an immense crop of walnuts in this district last fall, and thousands of bushels were put up carefully, in this way, all ready for shipment before the weather became warm; many more thousands were planted to grow seedlings from, for, notwithstanding the walnut transplants poorly when of considerable size, the one year seedlings transplant with as little loss as the average trees. There is no tree better adapted for planting to secure timber claims with than the black walnut, and none more valuable when the timber is grown. For this purpose the land should be plowed deeply, then harrowed to fineness and firmness, and furrowed out in rows four, six, eight, or ten feet apart. The nuts may then be planted as directed. It is best to plant thickly in the rows, then if too thick they can be thinned out, transplanting the thinnings, or selling them to the neighbors. They should be thoroughly cultivated, until large enough to shade the ground, and thinned out as necessary as they grow larger. A walnut grove thoroughly cultivated the first ten years will grow at least twenty feet high, while one not cultivated at all would only grow two to three feet in that time. D. B. WIER., LACON, ILL. Notes on Current Topics. ARBOR DAY. Why can not Illinois have an Arbor Day as well as Nebraska, or any other State. There ought to be ten millions of trees planted the coming spring within its borders--saying nothing of orchard trees--by the roadside, on lawns, for shade, for wind breaks, for shelter, for mechanical purposes, and for climatic amelioration. Nearly all our towns and villages need more trees along the streets or in parks; thousands of our farms are suffering for them; hundreds of cemeteries would be beautified by them, and numberless homes would be rendered more pleasant and homelike by an addition of one, two, or a dozen, to their bleak places. Can not THE PRAIRIE FARMER start a boom that will lead to the establishment of an Arbor Day all over the State? Why not? There is yet time. HOT-BEDS.
