more Hatches (i( the fpace of ground requires ) as it were I 
. in hxtfk, till we cotne to the top of the Hill^ and if we find I 
none in any of thefe Hatches.th^h farewell to that Hill. j 
7, But if we find any shoad in any of thefe Hatches, we 
keep our afcending Hatches in a diredtJine 5 and as we 
draw nearer the Load^ the deeper thie Shoad h ( as aforej 
. f roni th^ for face 5 but the nigher the Shelf h as fuppofe it be 
7 foot deepj and but half from the Shelf, then we prefently 
: conclude, the le?^^ to be within a fathom or 2 of us, and 
fo weleflen our firft proportion accordingly, as of that of 
1 2 fathom to 65 45 ^^ 15 as our conjefture guides u.% 
8* Sometimes it falls out^that v/emay over-fhoot a Load^ 
that is, get the upper fide ofit, andfo we loofeit^for which 
we have another ( counted alfo infallible^ Kule^viz. that 
finding shoad lying near the <S'<6e/f in'this Hatch^^nd finding 
none io the next afcending, we have over- (hot our Load. 
The remedy is eafie, which is 'to fink aigherrhe Hatch, 
wherein we laft found shoad, [ . 
9. At other times it may happen, that we' find a new 
shoad, that is, two dijfFerent Shoads in one Hatch , as fup- 
pofe in this Hatch we find our Shoad 8 foot deep , in the 
next we hope to find it at 10 foot 5 but at ^or^wemeet 
with a new Shoad, and Grewt5(which we diligently ob- 
ferve.)andat 10 we meet with our firfi: Shoad; Then, I 
fay, we have a certainty of another Lodd above the former, 
and it may be io Training up to the fecond^ v^e meet with 
, the 5hoad of a third* Neither is this diflbnarttto the opi^ 
nion andpraftife of the ancient Tinners, who Viaffirm, that 
7 Loads may lie parallel to each other in the fame Hi!!, but 
yetooeonly Majier-Loadi^ the other 6» ( 3 on eachiidej 
being the leiler concomitants* So may 5 lye in like mac?

% ic. Every Load has ( as it Vv^ere ) a peculiar coloured 
eanhj or grewr abcutir, which isfouod likewife with the 
Shoad in a greater quantity, the nearer the Shoad lies to 
the Load, and fo leflened by degrees about a ;J of a rniles ^
