assistance, has rendered them invaluable aid. Also, to Mr. Carl Purdy, of Ukiah, who from his wide experience, as a grower of our native liliaceous plants, has a knowledge of them shared by few or none, and who has generously placed at their disposal the results of his observations. They also tender their thanks to the Southern Pacific and the North Pacific Railways, who, by their generous granting of reduced rates and passes, have made possible a wider personal acquaintance with the flowers than could have otherwise been enjoyed.

San Rafael, Cal., October 15, 1897.
