Mr. Pringle passed through in sinking a well, within the walls of the 
factory, and which are as follows : 
1. Rubbish of buildings, - - ^ 8 feet, the level of high water. 
2. Clay, 2 ditto. 
3. Sea mud and wreck, - - - 1 ditto. 
4. Broken madrapore and shells, 6 ditto* 
5. Sea sand and shells, . - ^11 ditto. 
In this measure he still persists, though the water ouzes in so fast, 
that he has been obliged to sink a frame of wood, to keep it out. 
In the third measure the water was mephitic, and extremely offen- 
sive. As the depth increases it becomes less brackish, and, at pre-?

It is evident therefore that, at Mocha, the Tehama, to the depth of 
twenty-eight feet, is composed of marine productions, except indeed

The harbour of Mocha, formed by the two forts, and the spits of 
land on which they are built, is still gradually filling up. Dows 
cannot now lie in it ; and the sea, which once washed the walls, is 
now at some little distance. A longer period has shown this gra-^

close to the straits of Bab-el-mandeb, where the Egyptian fleet could 
once lie, but where there is at present little more than a foot of

The celebrated ancient mart of Moosa was probably at Mocha, 
from the appropriate description handed down to us of its excellent 
anchorage on a sandy bottom. But if so, it ceased to exist for 
many generations, till the accidental residence of a hermit, and the 
discovery of the coffee, again brought it into notice. The history
