of the clay and sand was distinct and followed the contour of 

 the pockets. 



4. — Gouffre. 



The cliffs in the cove to the east of La Moye Point are 

 capped by deposits of head, in which concretions of calcareous 

 tufa occur, of the same nature as at Divette and Fermain, 

 and corresponding to those referred to in Dr. Dunlop's paper 

 in last year's Transactions as " mannchen or piippchen." 



5. — & Ancresse. 



The peat in this locality has yielded a few additional 

 bones, chiefly of small animals. 



ROCKS. 



1. — Park Street. 



In sinking a well at Mr. Bartlett's house (late Mr. 

 H. R. Le Cheminant's) the rock was found to be blue gneiss 

 somewhat resembling the Richmond type. This rock was 

 remarkable in having its crevices to a considerable depth so 

 filled with calcite as to be impervious. Some of the calcite 

 veins reached 1 inch in width. At a greater depth, however, 

 the fissures became more open and water was obtained. 



2. — Charroterie. 



A well was also sunk on Mr. E. A. De Putron's property, 

 lately purchased from Mr. W. Collings. Here small veins 

 of lead ore (probably argentiferous^) were found. 



3.— St. Peter-Port Harbour. 



Rock has been removed during the year in various parts 

 of the harbour. Near No. 1 and the Courier Landings, 

 hard diorite was found. The same rock also occurred near 

 the New North Arm of the Old Harbour, but in a more 

 decomposed state and intersected by veins of red quartz f elsite. 



4. — Rocquettes Lane and Gravees. 



In the excavations for the drains in these localities 

 already referred to, the rocks were chiefly decomposed diorite 

 or syenite. As in the cuttings and quarries of Route Isabelle, 

 little or no gneiss was met with. A boss of hard undecom- 

 posed hornblende gabbro was encountered opposite Lisle 

 Terrace. In Rocquettes Lane the solid rock occurred in 

 rounded masses surrounded by thoroughly decomposed mate- 

 rial, and veins of amorphous diorite reduced to a loamy clay 

 were met with.
