work should be done, so that it is unnecessary to traverse the 

 ground again, and in order to illustrate practically the use 

 which might be made of these records not only in everyday 

 practice, but in pubhcations and for lecture purposes, a series 

 of typical views was shown by the aid of the optical lantern. 

 These illustrated several of the geological periods, the views 

 having been taken from actual Australian scenes, the large 

 rock masses illustrating granites, porphyries, limestones, 

 basalts, (fee. being first shown, and following them were 

 exhibited photographs of the polished surfaces of these same 

 rocks, together with photo-micrographs of sections of them, 

 giving upon the screen a magnification of 500 to 1500 times, 

 thus rendering the series complete. 



7.— M OUNT BISCHOFF. 



By H. W. FERD. KAYSER, M.E. 



The history of Mount Bischoff as a tin-produciug district 

 began from the 4th December, 1871, as on that day Mr. 

 James Smith, of River Forth, discovered tin ore at the slope 

 of the Mount ; and the first sample — a matchbox full — he 

 took to the estabhshment of Messrs. Moore and Quiggin,

 shining before those present, the question was asked, " Is it 

 silver ? " which the old doctor, being an expert, soon settled. 

 The full value of the discovery did not present itself to any of 

 these gentlemen then, as no doubt they all would have liked 

 silver in preference to tin. 



In August, 1872, Mr. Smith, in company with Mr. W. 

 M. Crosby and a small party of workmen, proceeded to 

 Mount Bischoff, and opened a track to connect Knole Plain 

 with the southern portion of the leased ground, and mining 

 began on the 14th December of the same year. 



In the middle of 1873 several tons of ore were sent to 

 Melbourne, which caused a good deal of attention among 

 mining men, and negotiations were entered into with a 

 syndicate for the sale of the mine. To effect this Mr. Wm. 

 Dick was selected to inspect and report upon the property. 

 After the report had been received all appeared to go on 

 well ; but, singular to say, after a certain amount of business
