Mr. H. says, that since he ‘tact eee it a aie has made a 
hollow inside the bole of the tree 10 ft. 10 in. x 8 ft. 8 in. in dimen- 
sions; and that another tree of the same species, growing at a short 
distance, which is also hollow, measures 69 feet outside girth, with 
a circumference of 46 feet of inside measurement. The price of 
timber of the Blue Gum is stated by Mr. Hull to be Is. to Is. 6d. 
per cubic foot at Hobart Town, and 5s. or 6s. in England; while 
Oak plank is said to fetch 7s. 6d. Mr. Hull mentions a Blue Gum, 
which, in the course of clearing land for the plough, on the estate 
of Tolosa, was cut down, the root grubbed up, and the whole split 
and cleared away at a cost of £7, having yielded sufficient timber 
to fence in a small paddock; while another specimen of the same 
kind yielded 58 tons of firewood, which, being sold at 7s. a ton, 
realized £20 6s: Mr. Hull observes, “the Blue Gum’’ tree attains 
in moist and rich ground a diameter of 24 to 30 inches in 20 years. 
The trees now growing in front of Government House, the largest of 
which is 5 feet in circumference, were planted 16 years ago. The 
two trees of the smaller, or White Gum species, which are growing 
in the Private Secretary’s garden, were planted the 28th December, 
1819, and are now respectively 6 feet 9 inches and 5 feet 7 inches 
in girth. 
A paper was read by Sir William Denison giving the results of 
some interesting experiments conducted by His Excellency on the 
culture of the Potato, under varying circumstances, as to distance 
between the rows and sets, the sort of manure employed, &c.
