These are just now receiving particular attention in every populous town. In a recent visit to Buffalo, we were especially delighted with their public grounds. Mr. F. Law Olmstead is the designer, and Mr. McMillan has the general superintendence. We doubt whether so much has been accomplished in any town for so little money, and that much done so tastefully, and in a general sense, so well. It would be a great treat to our readers if Mr. McMillan would give them some leaves from his experience in these lines.
