184 Memoranda regarding a Boring [No. 



sand during the day, one small sea shell and two agate pebbles were 

 met with. 



Second day, 13 feet Friday, I8th» — The sand was found to be moist at 

 6 inches. ^-^^ commencement, and to be freely mixed up with 



water as the boring proceeded, so that much time was lost in bak- 

 ing out the accumulating water with the water cylinder. Notwith- 

 standing which a depth of 13 feet 6 inches was arrived at by the 

 evening. 



Third day 17 feet 6 Saturday, IQtli.—On Commencing operations this 

 inches. ^ay, there was four feet of water in the hold, by rea- 



son of which, the auger, although penetrating to a depth of from 12 

 to 14 inches at each boring, nevertheless, on being brought to the 

 surface, was found to contain but a very inconsiderable quantity of 

 sand; and on being again lowered, 12 out of 14 inches before appa- 

 rently gained was now necessarily lost. It would in fact appear, that 

 the auger although well adapted t© boring, was, nevertheless under 

 the present circumstances, not well fitted for removing the sand ex- 

 cavated ; a vigorous application of the water cylinder, however, ena- 

 bled us by the evening to arrive at a depth of 17 feet 6 inches. The 

 soil both to-day and yesterday was extremely uniform, being a coarse 

 sea sand, with here and there one or two minute pieces of broken 

 shell. The borer, from the commencement had been continued in ac- 

 tion until the force of four men was insufficient (by reason of the 

 depth attained) to produce further movement, until in fact the au- 

 ger became jammed; — this uniformly occurred after excavating from 

 12 to 14 inches. 



Fourth day 23 feet Monday, 2\st. — We had now eight feet of water 

 0 inches. jn the hold : hitherto the auger had been accompa- 



nied in its downward progress by 2 nine inch protecting cylinders 

 of Iron (placed end on end,) each of 9 feet in length ; these being 

 very heavy, a small force only had been necessary in addition to their 

 own weight to make them keep pace with the auger, but we now 

 begin to find that increased depth renders this a matter of difficul- 

 ty — by the evening we had arrived at a depth of 23 feet ; but the 

 protecting cylinders had stuck fast. The soil, — ordinary coarse sea 

 sand, towards evening was distinguished by being mixed up with mi- 

 nute glittering particles (probably Mica.) 



Filth day, 24 feet Tuesday, 22nd.— We had now 121 feet of water in 

 3 iuchbs. the hold— continued hammering— lowered the pro-
