"We have letters occasionally condemning various matters of detail done in Fairmount Park, and with which correspondents we mostly sympathize. But we always take comfort when we consider how much worse things might be. Although the management of the park is in the hands of a commission, the members are naturally subjected to an immense pressure on all sides, and as long as a commissioner is but a human being, it is only possible for him to do the best he can.

We are very familiar with the difficulties which surround a great public enterprize like this, and in this light only wonder that the results are as generally creditable as they are, and we would rather encourage the commissioners in the good they are doing than harrass them for their mistakes; or perhaps more charitably for what circumstances make it impossible for them to do. And we are very glad to learn that there are a few steps of progress to be made in the park this spring, though the commendable economy of councils affords the park commissioners but limited appropriations. The superintendent, General Thayer, and Mr. Miller, landscape gardener, are busy in planting out trees in the park. Dr. Rothrock, professor of botany, on Wood's foundation, is to make a catalogue of the trees round Horticultural Hall to the foot of George's Hill, that they may be labeled and the catalogue may be printed. He is also to arrange the dry specimens of wood in the museum in Horticultural Hall. He is also to lecture on botany in that Hall every Saturday at 4 o'clock P. M., from April 20th to August 2d, at the cost of the Michaux legacy, by order of the American Philosophical Society.
