64 MEETINGS. 



1. — A depression to a point somewhat below the 

 present level to permit the formation of the lower beach. 



2. — An elevation above present level, perhaps con- 

 siderably so, when the head (presuming it to be of 

 sub-aerial formation) was deposited. 



3. — A deeper depression when the Capelles and 

 other high level beaches were deposited. 



4. — Another elevation when the peat deposits were 

 formed. 



5. — A depression, probably still in progress. 



ROCKS. 



The rock in Foulon Road, Rohais Road and Collings 

 Road, is almost everywhere decomposed, even to the extreme 

 depth of 44 feet reached near the " Beehive," but there are 

 occasional bosses and nodules of undecomposed rock consisting 

 in most cases of diorite. In Collings Road some of these 

 nodules are of the Hornblende gabbro variety, while at the 

 Couture end and also near Mahaut Cottages the crystals are 

 flattened as in " long grain," and this probably accounts for the 

 decomposed rock resembling gneiss referred to in last year's 

 report as having been noticed in Rozel Road. Rock, which 

 however may be fairly called gneiss, occurs near the " Bee- 

 hive." In most parts, but especially in Foulon Road, 

 intrusive veins of coarser grain occur as they do in the north- 

 ern part of the Island. Felsitic veins also occur, and are 

 numerous between " Wisteria Cottage " and the " Beehive." 



Near the Grande Maison, on St. Sampson's Road, a boss 

 of solid rock occurs, and is of the Hornblende Gabbro 

 variety. 



ALDERNEY. 



In the course of an excursion to this Island during the 

 month of July, 1901, the sandstone patch on the S.W. coast 

 was visited. A quarry is worked in it. In one spot the 

 sandstone was seen to rest on what appeared to be a boss of 

 decomposed granite. Although pebbles occur in the sand- 

 stone, it is not conglomeratic, as might have been expected 

 in the lowermost strata. Lower down the cliflf the sandstone 

 is seen in close proximity to syenite with large felsite dykes, 

 but the actual contact is hidden under the soil. There are 

 also small veins of felsite in the sandstone, and the sandstone 

 itself is somewhat altered. From this it might be inferred 

 that the felsite is of later date than the sandstone, but on the 

 other hand the veins are of much smaller size in the sandstone
