laden and towing a raft astern. 
That there was no islet in the place of the North Rocks when the 
islands were first settled (1611) is evident from the fact that none 
is mentioned by the early chroniclers and none is represented on 
Norwood’s accurate map of 1626. Indeed, it is recorded that Gov- 
ernor Moore (1612) made a voyage out to sea in order to find, if 
possible, an outlying island, but without success.* An island at this 
locality, even if small, could easily have been seen from the main 
island. Hence it would be safe to believe that the North Rocks 
were then not much larger than now, even if we did not have 
Norwood’s sketch to prove it. 
Figure 33.—North Rocks as drawn by Lieut. Nelson, about 1830, and published 
by Lyell, 1858. A, The largest rock, then 16 feet high, with two conspicu- 
ous side-lobes, a, b, and a small rock, c, near its base; ¢’, c’’, two smaller 
rocks where but one now stands. B, Next to largest Rock, then about 12 
feet high, strongly undercut at cc, cc. 
In Lyell’s Manual of Geology,t the author has reproduced a very 
interesting drawing of the North Rocks, made, as he stated, by 
Lieut. Nelson. Therefore, it dates from about 1830, for Nelson was 
the engineer in charge of the governmental works at Ireland Island 
in 1827 to 1833. This figure (see my fig. 33), if correct, shows that 
the North Rocks have changed somewhat during the past 75 years. 
The small rock, c, seems to still exist. 
The main rock has lost something from the height of the smaller 
peak (a, a), and one side-lobe seems to have been lost. One of the 
two rocks near it (¢c’, c”) has apparently disappeared ; the only one 
that appears in that vicinity in the recent photographs (fig. 23) has a 
crooked form like c’. The rock c” seems to have been destroyed. 
The rock B, in the foreground of this sketch, is represented as rela-
