To re-afforest the disafforested wilderness has of late occupied the thoughts of the thoughtful in our country. Dr. Lyons, for some time M.P. for the city of Dublin, gave to it much of his attention. He has been taken away, but his mantle has fallen upon another. Dermot O'Conor Donelan, Esq., J.P., of Sylane, near Tuam, teaches us how the people of other countries are enriched by their forests. Having made a tour through the unwooded mountains of Connemara, he subsequently in the present year made a tour through the wooded mountains of the Grand Duchy of Baden. His inquiries and the result of his inquiries in that prosperous country he published in a series of letters in the _Irish Times_ and _Freeman's Journal_. To give those letters _in extenso_, however instructive, would fill too many of our over-filled pages, but we may be permitted to make a few quotations from them. [Sidenote: FORESTS IN BADEN.] "It is a noteworthy fact," writes Mr. Donelan, "that from the class of lands similar to those that lie waste in Ireland, the recent progress of Germany is generally believed to proceed. Prussia, Bavaria, Saxony, Wurtemburg, Baden, and Alsace-Lorraine have a combined population of 40,644,000. The labour connected with the forests of those countries and their products have been estimated to be worth £9,450,000; and those earnings suffice for the maintenance of about 300,000 families." He then forms a painful contrast between Baden and Ireland--between the German mountain districts, and the mountain districts of the same kind in Ireland where there is a similarity of soil; but there the similarity ends.
