Prof. Rothrock is of the opinion that the early natives of California smoked the leaves of Nicotiaua Cleve-landii, A. Gray - a species only quite recently described. It is a small plant with small flowers, and it was found by Prof. Rothrock only in association with the shell heaps which occur so abundantly on the coasts of Southern and Central California. He states that perhaps of all the remains of extinct races so richly furnished by that region, none were so common as the pipes, usually made of stone resembling serpentine. The Tobacco of N. Clevelandii, Prof. Rothrock found by experience to be excessively strong. - Gardener's Chronicle.
