On the occurrence of coral on the Grand Banks.
Relative to the occurrence of corals on the slopes of the outer fishing banks, I beg to say that the place of greatest abundance of the Primnoa reseda more particularly-is on the eastern slope of Banquereau, in from 150 to 200 fathoms or more, and latitude 44° 28' N. This " spot," which is several miles in extent - the latitude given marks about its center - is covered to such an extent with a coral growth that it seldom happens that trawl-lines set on it are all recovered.
The fishermen have learned to avoid the place somewhat, and they have given it the name of " The Stone Fence," Stones of considerable size (as large as the fishing lines will lift) are not infrequently pulled up, and it is possible that a proper investigation of this locality might result in securing some rocks containing interesting fossils.
On what is called the "Middle Prong" of Banquereau, in 44° 13' north latitude and 58° 02' west longitude, in from 250 to 360 fathoms of water, I found considerable many corals in July, 1879, and among others several specimens of the gold-banded coral, the latter being more plentiful than i have seen it elsewhere. This place is small, however, not more than three-fourths of a mile in diameter, and would probably be somewhat difficult to find, unless the weather was fine and clear.
Referring to the last-mentioned locality, I find the following in my journal, under date of July 30, 1879, the vessel then being anchored in 205 fathoms, latitude 44° 14' north, longitude 58° 03' west:
"Four of our trawls were on the ' Spot,' which bears about southeast by east from the vessel, and is about two-thirds of a mile distant, to its nearest edge. It is about three-fourths of a mile in diameter; the bottom, 'catchy,' having a growth of corals of various kinds, including the following varieties: Gold-band coral (Keratoisis ornata), great tree coral (Paragorgia), bush coral,(Acanella normani), and treecoral (Primnoa Reseda) reseda)."
