REMAINS IN ENDSLEIGH STREET. 461 



described is the following at Gower Street Station, given by Mr. 

 Whitaker (op. cit. vol. ii. p. 321) :— 



"Made ground, 4 to 5 [feet]. 

 Sand and gravel, with yellow clay, 13 to 17 [feet], 

 London Clay, yellow at top, up to 5 feet, or above the line (rises 

 eastward)". 



The amount of yellow clay is not stated, but it is interesting to 

 note that it extends northwards in that direction. The London 

 Clay, which is stated to rise eastwards, evidently bounds the valley 

 which crosses Gower Place in a northerly direction. 



§ 4, Upper Wobitrn Place and the Eastern side op 

 Tavistock Square. 



Prom the south-eastern corner of Tavistock Square to the northern 

 end of Upper Woburn Place there is a fall towards the north in 

 the present surface of about 5 feet, and the excavations which have 

 been made show a fall in the London Clay, in the same direction, of 

 about 3 feet. The excavations were not opened out to the surface 

 continuously along this line, but tunnels were made, in places, 

 between the openings. The materials removed from the tunnels 

 which were brought to the surface consisted of dark blue clay, with 

 numerous septaria, fragments of iron pyrites, &c. The tunnels here, 

 being nowhere nearer than about 20 feet to the surface, were well 

 in the London Clay and below all the newer deposits, which did not 

 in any part reach downwards to more than about 14 feet from the 

 surface of the road. 



At the corners of Tavistock Square very wide excavations were 

 made, and excellent sections of the deposits were exposed, of which 

 the following are the details : — 



(a) North-eastern end of Tavistock Square, and extending into Upper 



Wobum Place, 

 Made ground, with stained clay at the lower part, 7 feet. 

 Yellowish clay, 1 foot. 

 Sand and sandy gravel, 5 feet. 

 London Clay. 



(b) South-eastern corner of Tavistock Square, and extending into Tavistock 



Street. 

 Made ground, 6 feet. 

 Yellow clay, 2 feet. 

 Yellow loamy sand, 1 foot. 

 Sandy gravel, 5 feet. 

 London Clay. 



§ 5. Southern sides op Tavistock and Gordon SauAREs. 



The excavations along this line were carried to depths from the 

 surface varying from 17 feet, at the south-western corner of Gordon 

 Square, to 25 feet at the south-eastern comer of Tavistock Square. 

 In Tavistock Square tunnels were made to connect the openings, but 

 in Gordon Square the excavations were carried along continuously.
