The cost of rams ought, strictly speaking, to be added to capital, and not deducted from Income; but these returns were made out in their present form at the request of a gentleman proceeding to the Colony with a limited capital, and who wished to know how much he might safely invest in sheep. APPENDIX No. IV. LIST OF GEOLOGICAL SPECIMENS, COLLECTED IN THE DISTANT INTERIOR DURING THE FIRST EXPEDITION, WITH THEIR LOCALITIES AND THEIR RELATIVE DISTANCES FROM EACH OTHER. It may be necessary to observe that the height of the Cataract of the Macquarie River above the sea, was ascertained by barometrical admeasurement to be 650 feet. The country subsequently traversed is considerably lower. The specimens refer only to the geological formation of the distant interior. Schorl Rock.--Colour blueish grey, fine grained, extremely hard. Composed of Tourmaline and Quartz. Forms the bed of the Macquarie at the Cataract, 75 miles to the N.W. of Wellington Valley. Decomposed Mica Slate.--Colour white; yields to the knife; adheres strongly to the tongue. Decomposed Feldspar.--Colour pale rose-pink; very fine grained; easily scratched with the knife; adheres strongly to the tongue. Both specimens immediately succeed the Schorl rock at the Cataract, in large smooth-sided masses. This formation may be said to terminate the rocks connected with the dividing ranges, since it is the last that occurs at their western base. A little below the Cataract, the county undergoes a remarkable change, and becomes extremely depressed. Porphyry with Feldspar.--Colour dull red, with white spots, or grey with red spots; very hard, compact, sonorous, magnetic. [See pp. 27 and 115.] Composition of Mount Harris, a hill called by Mr. Oxley, elevated about 170 feet above the level of the plains. It lies 65 miles to the N.N.W. of the Cataract, and is about 16 miles distant from the first of the marshes of the Macquarie. Porphyry with Feldspar.--Colour grey with red spots, similar to the last. Was not observed to affect the needle. Formation of Mount Foster. Mount Foster is more than 200 feet in height, and lies about 5 miles to the N.N.W. of Mount Harris. From the summit of both, Arbuthnot's range is visible, bearing nearly due east, distant 70 miles. [See page 28.] Quartz Rock varieties--Slaty Quartz varieties.--Composition of the first elevations to the Westward of the marshes of the Macquarie, called New Year's Range, a group of five hills. The loftiest about 200 feet in elevation; distant about 80 miles to the N.W. of Mount Harris. Granite.--Colour red, coarse-grained. Composed of Quartz, Feldspar, and Mica. Granite, Porphyritic.--Colour light red. Both occurring in the bed of New Year's Creek, traversing it obliquely, and are visible for a few hundred yards only. This granite occurs about 16 miles from the Range in a N. by E. direction.
