cottage. This quarry is the only place where I observed the rock in 
situ; but Mr. Slorne, who lives on the opposite or south side of the 
Hill, informed me that the same limestone was formerly worked 
immediately adjacent to the dilapidated cottage. I think it was from 
the latter place that Mr. Slorne procured a large number of stones 
built into the front wall of his house, and crowded with one or two 
species of fossils. 
About a mile to the north of the quarry, and just before as¬ 
cending the hill on which the rectory of Artrea is situated, some 
beds of a dark red freestone are worked, evidently a portion of the 
so-called “ New Red Sandstone,” which forms so much of the surface 
rock in the north of Tyrone. 
Returning to the south, Tullyconnel Hill itself is so masked with 
drift, that I was unable to ascertain the nature of its constituent 
rock; but the general impression in the neighbourhood is, that it 
consists of a freestone similar to that which occurs near the rectory 
of Artrea—a view somewhat countenanced by the occurrence of a 
bed of deep- red freestone at the bottom of a well in Mr. Slorne’s 
yard. Several blocks of this rock were lying about the mouth of 
the well at the time of my visit. 
At Annaghone, situated about a mile further south on the road 
leading to Stewartstown, beds of carboniferous limestone, with se¬ 
veral of its characteristic fossils, are exposed, dipping to the north¬ 
east, at an angle of about 17 degrees. 
Owing to so small a portion of the magnesian limestone being 
visible, there is a difficulty in ascertaining its inclination; but as it 
lies in the direction of the dip of the carboniferous limestone beds at 
Annaghone, there cannot be any doubt of the latter passing under 
the former, as represented in the annexed section. Respecting the 
red freestone near Artrea rectory, I have represented it, in accord-

Section from Annaghone to Artrea. 
a. The dilapidated cottage adjoining the road leading from Artrea to Tullyhog. 
b. Site of the magnesian limestone quarry situated in Mr. Beatty’s field. 
c. Quarry of red freestone at the bane of the hill near Artrea. 
N. B.—The section does not extend to the Annaghone quarries and limekiln ; merely to an 
outcrop of Carboniferous Limestone on the road, a little to the north of them.
