The corals of Delafield, pp. 185-193 PDF (2.5 MB)
The Corals of Delafieil. 193 nature has herself classified this fauna, and even then we must not expect to find divisions, but rather connected branches of one central type. The small collection hastily gathered by an exploring party from a little mound of debris must necessarily represent but a small proportion of the life that really existed in the teeming seas of that geological epoch. Amateur geologists have here a rich field for original work, and may find unlimited opportunity for study and investigation. 13
