Open Letters Mr. C. G. Pringle. On the twenty-seventh of November for a few hours I had the pleasure of the company of Mr. C. G. Pringle, of Charlotte, Vermont, who is on his way home from northern Mexico, where he has again spent the summer collecting plants. All who have seen his specimens know that he is a prince among collectors. He reports the season as unfavorable for his work, though he estimates that he has secured at least 1,000 species. Next year he anticipates going on to higher grounds in the same country. He thinks it is a rough, dangerous way to live, some of the time among people who would not hesitate to kill him merely for his clothes, still he is full of enthusiasm and likes his work. There is a perpetual fascination in finding new things as well as in meeting with old friends among his plants. Mr. Pringle appeared in good health and spirits. The time passed too quickly to hear all he had to tell of his journey and his acquaintance with botanists in various parts of America. Michigan Agricultural College. W. J. BEAL.
