I found Mentzelia ornata growing on the bank of the American Creek, near Chamberlain, Brule co., Dakota. It was just at sunset and it had fully expanded its large white and fragrant blossoms, for it is a real night bloomer. This being the first time I had seen it, I felt like a boy with his first boots - highly pleased. I have cultivated it since and it makes a fine garden plant with its delightful fragrance. Those who desire to botanize this locality should take, in addition to Gray's Manual, the Synopsis of the Flora of Colorado, by Thomas C. Potter and John M. Coulter. This will enable them to determine the names of whatever they may discover, with few exceptions. The bluffs around Chamberlain rise to the height of 475 feet above the Missouri River, and from the nature of the soil, the ravines are of extraordinary depth, giving shelter and shade to many plants and shrubs that I did not expect to find there. A large bed of Yucca is found there, which is different from filamentosa, and has a striped leaf like angustifolia. It was in full bloom at the time I visited it.

Many of the flower stalks are 7 feet high I also found the Opuntia Rafinesqui and Mis-souriensis, Solanum triflorum and Solanum ros-tratum, CEnothera albicaulis and O. serrulata, Gaura coccinia and a very pretty Verbena, with fine cut leaves like the old Imperitrice Elizabeth, which might be useful for florists to cross and breed hardy varieties from. It would be too long a list to encumber your valuable pages with, to give you all the plants that grow there, so I will confine myself to a few shrubs, such as Rhus aromatica, Shepherdia argentea, Symphoricarpus occidentalis, Amorpha fruticosa, and Glycyrrhiza lepidota. No one who visits Dakota in search of plants can be disappointed. The prairies are in a blaze with showy Liatris, Gerardia, Cir-sium and Helianthus, several Psoralias - amongst others, esculenta, and the modest Oxalis violacea. Should the individual who visits Chamberlain not be a plant enthusiast, he will, nevertheless, be well repaid for his journey. The scenery is at once beautiful and picturesque. As you stand on the bluffs, back of the town, you are at an elevation of 1,500 feet above the sea level. You can trace the winding course of the grand old Missouri for miles and miles, and tepees of the Brule Indians are visible in the distant southwest.

Here, we may say, we are the dividing line of civilization and savage life. Milwaukee, Jan. 16th, 1887.
