In education, chemistry has steadily grown in importance, until a single university may have need of as many as twenty chemists in its teaching staff, teaching not only what is already known, but also the art of research. As a disciplinary study, chemistry ranks high in the college curriculum, and it opens the way to a new learned profession, equal in rank with those of more ancient standing. For the material advancement of mankind the nineteenth century has done more than all the preceding ages combined, and science has been the chief instrument of progress. Scientific methods, experimental investigation, have replaced the old empiricism, and no man can imagine where the forward movement is to end. Hitherto research has been sporadic, individual, unorganized; but fruitful beyond all anticipation. In the future it should become more systematic, better organized, richer in facilities. Through laboratories equipped for research alone the twentieth century must work, and chemistry is entitled to its fair share of the coming opportunities. The achievements of the chemist, great as they have been during this century, are but a beginning; the larger possibilities are ahead. The greatest laws are yet undiscovered; the invitation of the unknown was never more distinct than now. MOUNT TAMALPAIS. BY MARSDEN MANSON, C. E., PH.D. Mount Tamalpais is the southern and terminating peak of the westerly ridge of the Coast Range, which confronts the Pacific Ocean from the Golden Gate to the Oregon line. Its outliers form the bold headlands which skirt the Golden Gate and adjacent waters to the north, and which bound the peninsula constituting Marin County. The spurs extending to the east reach the shores of the Bay of San Francisco, and inclose small alluvial valleys of great fertility and beauty. In some instances these valley lands are fringed by tidal marshes, in part reclaimed and under cultivation. The top of the mountain breaks into three distinct peaks, each reaching an altitude of nearly half a mile above sea level, although bounded on three sides by tidal waters. No land points visible from the summit, except those bounding the apparent horizon, reach equal or greater altitude. The mountain is therefore a marked feature from all parts of the area visible from its summit, which area has an extent of about eight thousand square miles. The adjoined photographic reproduction of a portion of a relief map of the State gives a general idea of the adjacent land, bay, and ocean areas. The westerly group of islands, opposite the Golden Gate, are the Farallones. The bold headland northwest of the Gate is Point Reyes; it protects from the north and northwest winds the anchorage known as Drake’s Bay. The strip of water between the adjoining peninsula and the mainland is Tomales Bay.
