growth of young is good enough to yield an average of about 15 
bushels per day to the tonger; but on the very scattering and 
depleted areas further removed from the ridge the young growth is 
sparse.

FLAT ROCK AND ADJACENT SMALL BEDS. 
Flat Rock is a small bed bearing a dense growth of market oysters 
lying in the southeast corner of Public Ground No. 6, Warwick County. 
The examination of this rock was not satisfactory, as owing to an 
error in platting in the field certain positions supposed to be on the 
bed proved to be on adjacent planted beds. The single examination, 
in connection with traversing lines of chain readings, indicates a 
growth over the entire area which will yield to the tonger an average 
of about 9 bushels of market oysters per day. There were practically 
no small oysters or shells, and there was some reason to believe that 
the place had been planted, though it was fully 200 yards inside of the 
Baylor lines. 
North of Flat Rock is a small depleted area, covering about 7 acres > 
on which there are about 26 bushels of market oysters and 16 bushels 
of young oysters per acre, and on which it is computed that a tonger 
could take not over 2 bushels of oysters per day. 
West of Cruiser Rock is another unnamed bed of very scattering 
oysters. Its area is about 5 ^cres, with an average of 42 bushels of 
market oysters and 55 bushels of seed oysters per acre, and it is esti- 
mated that a tonger could take about 3^ bushels of oysters per day. 
Northwest of Flat Rock, at intervals of about 400 yards, are two 
small beds where the water does not shoal, on which no deter- 
minations were made except with the chain. The indications are of 
very scattering growths. The areas are about 5 and 2 acres, respec- 
tively. The data relating to the several beds examined are as follows :
