and, with a slight inclination, ascends towards the eastern. i 
We will now describe more particularly the appearances 
of these dykes, veins, &c.: they rise at all angles through 
the accompanying strata; they are frequently parallel to each 
other, and even to the planes of stratification ; they generally 
either terminate suddenly in the rock at one or both extre- 
mities ; in the latter case they answer the description of con- 
temporaneous veins ; these extremities are others. pointed or 
forked. 
The accompanying diagram (plate 6, fig. 1,) will afford a 
better idea of what it is intended to describe. 
Isolated quarter moonshaped pieces and patches, varying from 
the size of the hand to that of the bodys are more common, 
(plate 6, fig. 2.) 
It is worthy of observaticn that the small quarter-crescent 
shaped pieces occur together by twos and threes in a parallel 
order, and that the trap, of whatever shape, generally has- an- 
gular corners, and terminations. Channels and hollows are 
sometimes seen in the face of the rock, which are owing to 
the removal of the trap formerly occupying these vacancies. 
It is not, however, merely as veins, beds, and distinct concre- 
tions that this trap is observed; it occurs, particularly in the 
higher parts of the Saguenay, in mountain masses bearing little 
appearance of stratification ; sometimes in masses in which its 
stratification will scarcely admit of a doubt, and sometimes it 
is rendered so evident by alternating with other stratified rocks, 
that no uncertainty can exist on the subject. 
The La Boule, by projecting so much into the river, occa- 
sions, when the tide is falling, a strong current and counter ed- 
dy. Not being able to surmount this current, the boat drop- 
ped into the eddy, and running along the base of the mountata 
on its south-eastern side, turned into asmall cove, where the 
height of La Boule was found by an observation to exceed two
