lands adjoining, as the majority of persons prefer purchasing go- 

 vernment building-lots to obtaining only leaseholds on the private 

 townships. 



In addition to the town reserve of Stanthorpe, it will very 

 shortly be necessary to lay out another reserve on the Severn river, 

 about fifteen miles lower down, somewhere in the vicinity of 

 Accommodation Creek. This will be more especially required in 

 the event of the lodes in that locality proving equal to the anticipa- 

 tions of the proprietors, as the working requisite to develop them 

 properly will give employment to a large population. 



It is not easy at present to form any very accurate estimate as to 

 the number of persons that will be required within the next twelve 

 months to enable selectors to fulfil the conditions required by the 

 clause of the Act under which the Mineral lands have been acquired ; 

 but it is scarcely possible that they can be complied with unless, at 

 the lowest computation, 5000 persons are employed, which number, 

 allowing a fair proportion for persons engaged in other callings, 

 including females and children &c, would not give more than three 

 persons to each forty acres. 



In reference to the probable time that will be required to work 

 out the known beds of alluvial tin-ore, it must necessarily depend 

 upon the number of persons engaged in it and the nature of the 

 seasons ; but under any probable conditions it is not likely that 

 they will be so far worked out within the next three years as to 

 occasion any diminution of the population below from 5000 to 8000 ; 

 and the development of workable lodes would, from necessity, per- 

 manently establish a much larger population. 



I have &c,

2. Observations on some of the Recent Tin-ore Discoveries in New 

 England, New South Wales. By G. H. E. Ulrich, Esq., E.G.S. 



The discovery of tin-ore (cassiterite) in the province of New 

 England, New South Wales, was brought under the Society's notice 

 by a letter from Mr. G. Milner Stephen, F.G.S., of Sydney, read at the 

 December meeting, 1871* ; and finding from the discussion thereon, 

 that the subject is not without interest to the Society, I beg to 

 offer the following further observations made during a recent visit 

 to that stanniferous country. 



The district to which these remarks refer forms, as as it were, a 

 hilly high plateau of the Australian Alps, of which Mount Ben Lo- 

 mond represents here the highest point, with an elevation of nearly 

 4000 ft. above the sea-level. According to my observation, the pre-
