fecurity, even in the darken nights, provided oidy 
they could fee the lights: and this is the more mate- 
rial, as, in dangerous weather, it is frequently the bed 
and mod fecure retreat between the Thames and the 
Tyne ; but the difficulty of entering it, for want of 
proper helps, oftentimes obliges (hips to keep the fea, 
not without great difficulty and hazard, when they 
might lie here in perfect fafety. 
1 have endeavoured to g.ive fome idea of the ap- 
plication, I propofe, in the annexed chart, [Fig. 2 ] 
which is meant only as a rough draught of the ge- 
neral defign, and not as an accurate delineation of 
what mud depend upon a future furvey, whenever 
the new lights diall be eredled. 
The drong black line is intended to reprefent the 
high water mark : the fpace included within this, 
and which is infcrlbed Spurn Point, as well as that 
inferibed Kilnfea Common, is ground, which the 
fea never overflows; but all the fpace between thefe, 
where the Angle line only is continued, is frequently 
waflied over by the fea, the land being there reduced, 
at the time of high water, to a meer bank of only a 
few yards wide. 
The dotted line furrounding the drong black line 
reprefents the low water mark ; and the other fpaces 
included within dotted lines, and inferibed Trinity 
fand, the bull, crofs ridges and broken ground, and 
done banks, are fuppofed to reprefent four fands, the 
two former lying within, and the two latter without 
the mouth of the Humber. 
Through the two points B and C, reprefenting the 
fuppofed new lights, are deferibed, according to the 
rule above laid down, two feries of feginents, one
