army will render this hill, at a future period, a favorite re: 
sort. 
8. Forts marked No. 3, on Marshall’s Map, near the S.W. 
of Prospect Hill have some of their bastions entire, but the 
surface is cultivated, and part of the outline destroyed. 
9. The Cambridge Lines, situated upon Butler’s Hill, ap- 
pear to have consisted of six regular forts, connected by a 
strong entrenchment. The most Northerly of these forts 
is perfect, with the exception of one of its angles destroy- 
ed by the road, it appears as if just quitted by the army of 
America, its bastions are entire, the outline is perfect, and 
it seems a Chef d’ceuvre of the military art. The state of 
preservation in which it is found, and the motives which 
led to its erection, all confer a high degree of interest up- 
on this fortification. May it continue uninjured for a long 
period of years, with no other foe but the assaults of 
time ! 
A square fort may be seen near the southern extremity 
of these lines, in fine preservation, it isin a field within 
two hundred yards of the road to Cambridge. As it was 
near the head quarters of the army, it must have been of-

alone would render it an object of interest ; but the pro- 
prietor appears to have wanted no inducement but his own 
mind to preserve this monument of times which are gone. 
The eastern rampart is lower than the others, and the 
gateway with its bank of earth still remains. 
The other forts and batteries of this line of defence, 
which constituted the firmest bulwark of the American ar- 
my, are all levelled with the ground, and the intrenchments 
which were raised and defended by warriors, are now em- 
ployed in the peaceful pursuits of agriculture. 
10. The second Line of Defence may be traced on the 
College green at Cambridge, but its proximity to the Pub- 
lic Halls may have produced some inconvenience, and 
it has been carefully destroyed.

the northern shore of Charles river, near its entrance inte
