sand and gravel on surface. Tlie gullies are not rich by any 
means, in fact no tin worth mentioning can be found in any one 
gulley or creek about here, they have such a rapid fall that the 
water runs off nearly dry within two days after a heavy thunder- 
storm. This only (the want of water) is the great drawback to 
Kangaroo Flat and its vicinity ; also capital is wanted to give it 
a fair trial. The tin lies below a volcanic basalt formation, and 
the wash-dirt is a regular river-bed sandy drift, with good tin, 
and below this is a cement in ■which in some places the tin is 
very thick. This cement is very hard, in fact requires to be 
crushed by some stamping process to extract the tin. The 
bottom is composed of metamorphic granite. The sinking is 
from 10 feet to 70 and 90 feet deep, but the Hall Bros, have 
driven tunnels into the hills, having in some of them tramways 
laid. ]Vo work of any account in the way of tin-raising has 
been done this last six months, on account of the p)rotracted 
drought. 
In one portion of Messrs. Hall Bros, property here, stanniferous 
wash, eight feet thlch^ which would prospect from \ oz. to 1 oz. 
to the dish (tin prospecting dish) has been traced into the hill a 
distance of 100 feet. The proprietors deserve great credit for 
the enterprising manner in which they have prospected most of 
their numerous selections in this neighbourhood. That a very 
rich lead or numerous leads of rich stauniferous dirt exists in this 
vicinity there is every indication. 
At the Siigarloaf Mountain, 3 miles west of Kangaroo 
Flat, and 16 from Vegetable Creek, also the property of Hall 
Bros., tin has been found, with very good prospects, 200 feet 
above the bed of the creek. It is one of the highest mountains 
for some distance around, and stands by itself in a sort of a 
hollow, with two gullies of good size on either side. The wash was 
followed into the hill by tunnels, but found to dip so suddenly 
as it were into the centre of the mountain, that many fancy it is 
a basin. The wash was very good as far as it was tested, a 
distance of 200 feet ; but water having been struck, and the 
ground proving very treacherous, requiring a good deal of timber- 
ing, all further operations were abandoned tor the present. 
The bottom is metamorphic granite, and the stanniferous "wash 
consists of round grains of tin ore (black) with double six-sided 
pyramids of quartz, also quartz pebbles, which are greatly water- 
worn, often found in the shape of hen’s eggs, and a quantity of 
small pieces of white topaz and zircons in a decomposed white 
felspar (albite), almost in a state of China clay. [A small speci-
