This department the reader will find particularly rich in contributions this month, which shows the widespread interest which is taken in intelligent study of nature. We are glad that this so. We neglect no item of progress that is at all likely to interest the newest novice in horticulture, or that may tend to put money in the purse of those who follow horticulture for a livelihood, but even to these there is an additional pleasure in knowing how the flowers blow and the birds sing, and it is gratifying to us to find by so many contributors to this column, that the world is coming to think more so as it grows. Besides, knowledge is power.
