deposits of recent origin, he described the extensive accumulations 

 of drift-gravels and boulder-clay. A single boulder near the Shan- 

 nonville railway- station was said to cover an area of about 5 acres, 

 and to have a thickness of 100 feet. The evidences of glacial action 

 over the whole country were referred to, and the direction of ice- 

 marks cited from several localities. Below the posttertiary deposits 

 the rocks consist, in the southern townships, of Lower Silurian lime- 

 stones referred for the most part to the Trenton group, and, in the 

 northern townships, of a large series of metamorphic rocks, supposed 

 to be of Lower Laurentian age. Bosses of syenite and gneiss pene- 

 trate the Silurian beds to the south of the main Laurentian mass ; 

 and several outliers of Trenton limestone point to the former ex- 

 tension of the Silurian rocks northwards. All the minerals of eco- 

 nomic value are confined to the Laurentian area. 



Gold was first discovered in the county of Hastings in 1866. The 

 author described in detail the singular occurrence of the metal at 

 the Richardson Mine in Madoc, where it was found in two pockets 

 associated with a peculiar black carbonaceous substance, a ferru- 

 ginous dolomite, and ochre-brown iron-ore. Assays of the sur- 

 rounding rocks showed the existence of gold even at a considerable 

 distance from the mine. Mention was also made of several other 

 gold mines, in Madoc, Marmora, and Elzevir, from which specimens 

 were exhibited, and analyses of ore quoted. 



The iron-ores of Hastings occur partly as magnetic oxide and 

 partly as haematite. In addition to the well-known " Big Ore- 

 bed " and the " Seymour bed," the writer called attention to some 

 new localities of magnetic ore in Madoc. The deposit of hoematitc 

 called the "Kane Ore-bed" was discovered by the author some 

 years back; and from ancient workings in this bed (apparently 

 those of the Indians, who may have used the ochre as war-paint) 

 he has obtained bone needles and other objects of human workman- 

 ship. Attention was then directed to a large deposit of specular 

 iron-ore in Hungerford, hitherto undescribed, and to the pyrrhotine 

 or magnetic pyrites of Madoc. 



The paper concluded with a notice of the galena and other less 

 important minerals of the county. 



2. "On the distribution of Flint Implements in the Drift, with 

 reference to some recent discoveries in Norfolk and Suffolk." By 

 J. W. Flower, Esq., F.G.S. 



The author noticed some recently discovered localities in the 

 valley of the Little Ouse which have yielded Flint Implements, 

 viz. : — at Broomhill, about 350 feet from and 5 or 6 feet above the 

 level of the river ; at Gravel Hill, about 1 mile from and 10 feet above 

 the river ; at Shrub Hill, about 1 mile from and only a foot or two 

 above the river ; and at Lakenheath, nearly 3 miles from the river, 

 and 60 feet above it. In the first three of these localities the worked 

 flints are in coarse gravel, resting immediately on the Cretaceous 

 beds (chalk in the first and second, gault in the third), and overlain 

 by regular deposits of gravel and sand. The implements resemble 

 those of Acheul, Thetford, and Salisbury, but present some pecu- 

 liarities, from which the author inferred that each place had its own
