Our Indiana friends should remember that in that State, Arbor Day occurs April 11th. A general effort is being made to interest the teachers, pupils, and directors of the district schools in the observance of the day by planting of trees and shrubs in the school yards. It is to be hoped that the people generally will countenance the observance in all possible ways. * * * * * Prof. S. A. Forbes writes us that there is needed for the Library of the State Natural History Society, back numbers of THE PRAIRIE FARMER for the following years and half years: 1852, 1855, 1856, 1857, 1858, 1859, 1860, second half year of 1862, 1864, and 1874. Persons having one or all of these volumes to dispose of will confer a favor by addressing the Professor to that effect at Normal, Ill. * * * * * Florida vegetables are coming into Chicago quite freely. Cucumbers are selling on South Water street at from $1.50 to $2 per-dozen. They come in barrels holding thirty dozen. Radishes now have to compete with the home-grown, hot-house article, and do not fare very well, as the latter are much fresher. Lettuce is comparatively plenty, as is also celery. Apples sell at from $4 to $6 per barrel, and the demand is good. * * * * * Mercedes, the famous Holstein cow owned by Thos. B. Wales, Jr., of Iowa City, died on the 17th inst., of puerperal fever, having previously lost her calf. Mercedes enjoyed the reputation of being the greatest milk and butter cow in the world. Her last year's calf it will be remembered was sold for $4,500. The cow and calf just dropped were valued at $10,000. The butter record alluded to was ninety-nine pounds six and one-half ounces in thirty days. The test was in 1883. * * * * * The Mark Lane Express in its review of the British grain trade last week says the trade in cargoes off coast was more active, but the supply bare. California was taken at 39@41s per quarter. Two cargoes have gone to Havre at 39s 11-1/2d@39s 3d without extra freight. Seven cargoes have arrived, ten were sold, eight withdrawn, and one remained.
