dwelling of his father, near which the Sewree and Parell roads separate
a re pierced, which again appears around the house of Mr. Wells, horse
dealer, and by the side of the railway opposite Government House
extending towards Matoonga. This I assume on very imperfect
grounds, as will be seen, to be the second fresh water bed in the de
scending series: the presumptions are in favour of the hypothesis, and
there seems nothing to oppose to it in the present state of our knowledge.
These remarks have been made general to avoid repetition : if the
reader will turn foi ward to where the Baboola Tank is described,
he will find a minute account of the appearance of these beds.
46.-3, 4, and 5, Lower Baboola Tank and Jail Well Beds. The
3 rd, 4th, and 5th beds in the descending series are so thin, so imperfectly
marked, and have been observed at so very small a number of points,
that the reader is referred to the paragraphs further on, where descrip
tions of them appear.
47 6 .— Chinchpoogly and Parell Hill Beds Following the lino
of road from the Grant College through Mazagon to the sea shore,
that from Mr. and Colonel Dickenson’s houses to Chinchpoogly, and
that from Mahim Wood to Parell Hill, we have very tolerable means
of examining the rocks in three parallel lines at right angles to their
outcrop. The beds 3, 4, and 5, ought to cross this line if comforma-
ble with the others, but they are so very thin, and so easily lost sight
of, that it is impossible to say whether they are non-existent, or are
merely out of sight—they at all events scarcely affect the general
character of the large mass of trap which now intervenes : it is
nearly a mile across, and is much the most massy I have met in with, its
eastern edge resting on the ridges of Parell, Chinchpoogly, Mazagon,
and Nowrojee Hills (Dungaree,) where it is much broken up, and
disturbed, and Fort George. The sedimentary rock manifests itself in
masses at Chinchpoghly, where it extends about thirty feet vertically
up the hill, and about 100 horizontally, and is probably in actual
measure forty feet thick : it dips nearly due west, at an angle of from
8 to 15°. Ifc is of a light yellow ochrey colour, hardened over the
Mpper surface by the contact of the trap, which is much decomposed
and bouidery at the point of contact. The crops of this bed are
conspicuous all along, stretching away nearly due north, forming the
upper formation of Chinchpoogly Hill; along the line of the Gardens
