Second growth redwood for poles. This pole was set on a trap line to the San Mateo county quarry. The poles were furnished by the subscriber and were of a very rough, much tapered type. Although set in 1924, the pole was stubbed in 1928, although from examination, Assistant Engineer C. E. Young thought that the stubbing was not necessary as the area of heartwood remaining after the sap had decayed was sufficient to maintain the pole. However, this pole was heavily loaded with swithch mechanism. E.F., Feb. 1929
