The second group, which comprises the Bismarck, King Atilla, Lady Anne, 
■Providence, Flying Pig, Tichbome, Idaho, Explorer, Great Korthern, Devon and Corn- 
Wall, Empress of India, Alliance, Mowbray, Honest Lawyer, Fourth of July, Columbia, 
^rid Eureka, runs mainly north and south and at right angles to the lines which denote 
outcrops of the stratified rocks. Their underlie is always to tho east. It is 
probable that they belong to a period subsequent to the first series of fissures. 
The gold occurs in a matrix of laminated quartz, without much pyrites or galena 
foxcept in the case of some of the mines of the Eastern Hodgkinsou). There is 
oonsequently little difference in the productiveness of the stone above and below the 
^ater level. Blanks are met with hero and there in most of the reefs — i.e., spaces con- 
taining neither gold nor quartz, but only a brecciated ganguo of sandstone and shale 
^ragments. The gold almost always occurs in rather narrow “shoots,” most of which 
® out (although the quartz may continue) at less than four hundred feet in depth, 
is, however, no reason to doubt that at greater depths other shoots will yet be 
discovered. 
^ In addition to the reefs around the townships of Thornborough and Kings- 
^moughj Deep Creek, 'Woodville, the Eastern Hodgkinson, and Northcote are or have 
j^®n important centres of mining industry. Antimony lodes occur at Woodville and 
di^thcote. At the latter largo smelting works have been erected. 
The strata of the Palmer Gold Field are in all probability of the same age as those 
° Ihe Hodgkinson Gold Field. Between the Ida and Maytown the shales or slates and 
ddstones have a pretty uniform north-north-west and south-south-east strike, and are 
for ^ ^drtical, with a slight dip to west-south-west. From Maytown, down the Palmer 
about a mile, similar rocks, also nearly on edge, strike mainly north and south, with 
th^ *I'P to the west. Farther west the character of the stratified rocks changes ; 
hed^ of a more altered type, consisting mainly of slates and schists. A limestone 
j, of immense thickness belonging to the same series runs south-south-east from 
^Orville for at least twenty iniles towards the Mitchell. I failed to obtain any 
^ ssils from this limestone, which is generally blue and unaltered, but at times becomes 
Q§^oy crystalline marble. The same limestone is traceable from Palmerville northward. 
east side of the Cooktown and Palmerville Road, about four miles north of 
by y the limestone is vertical, and strikes north and south, and is accompanied 
Qj, slates (with a similar dip and strike), which occupy the floor of the valley 
Rre^^^* ^^^•’ough which the road and telegraph line are carried. The limestone here is a 
ojjj ’ ^y'^f^'Uine marble, although its surface is blackened by a crust of lichens. The 
for^ observed were Crlnoid stems, too imperfectly preserved for specific or even 
bei determination. The limestone forms a cliff of about a hundred feet in 
®frat ’ weathered into the most fantastic and even grotesque shapes. The 
^isht\°^ formation are succeeded unconformably by the Desert Sandstone on the 
of the Palmer, from Palmerville up to Maytown.
