California mines and minerals . Gallows Frame at the Oneida Mine, in Process of Enclosure. It may be said that the incline is the preferable means of pros-pecting, developing and working the mine to moderate depth, whilethe vertical shaft is much the better for operations to great depth. Beginning \vith a virgin mine on the lode, the start is very properlymade with an incline following the vein. After operating to depthsof 800 or 1000 feet it is found that the expense of repairs is rapidlygrowing, while the capacity of the incline is rapidly is the time to stop and inaugurate a better system of work, ifthe showing justifies it. But an oversanguine spirit, impatience andimprovidence are apt to prevail. If in good ore, it is generally pre-ferred to follow the old system as long as it pays expenses, with thehope of finding something still better. An unfortunate turn destroys THE MOTHER LODE 69 confidence and credit, and the mine, which might have paid well underbetter management, is closed indefinitely
