460 QUEENSLAND AGRICULTURAL JOURNAL, [1 Nov., 1899. 
ascertain if the surface of the ground in any of these localities was of such @ 
nature as would permit artesian water from a suitably situated central bore, or 
bores, to flow by gravitation 1o surrounding grazing farms, and if any particular 
site was specially advantageous. os 
The result of such inspections and surveys was that a site was selected as 
supplying the necessary conditions on Bando Resumption, about 35 miles 
northerly from Cunnamulla, and about 21 miles westerly from Coongoola 
Railway Station, Warrego district. ‘Trial surveys and levels were then taken to 
ascertain the area that would probably be watered from the proposed site of the 
bore, after which eight farms, varying in size from 16,000 acres to 20,000 acres 
each, comprising a total area of 145,800 acres, were surveyed round the site. 
After this was done the contract was let for putting down the bore, which was 
finally completed and handed over to the Department by the Hydraulic 
Department in April, 1898, the continuous flow from the bore being then 
2,100,440 gallons during each 24 hours, the temperature of the water 130 
degrees Fahrenheit, and the total depth of the bore 2,090 feet. The water, 
after analysis, was found of exceptional purity, and fit for use in any manner, 
even for human consumption. 
Further surveys were then made and levels taken in order to ascertain the 
exact positions for channels proposed to be constructed to convey the bore 
water to each farm. After this had been ascertained, and plans, specifications, 
&c., prepared; tenders were called in the beginning of the year for the necessary 
work. ‘Chis work was completed some little time ago, and the eight farms were 
thrown open to selection on the 3rd October last, it beng intended that seven 
of the farms, comprising a total area of 125,800 acres, shall be watered from 
the bore, it being doubtful in the case of the remaining farm if the water will 
reach it. The rents have been fixed very moderately, ranging from 14d. to 23d, 
per acre, which includes everything, The maximum area for selection is 20,000 
acres, and terms of leases of the farms 28 years each. 
Since the above was written, we learn that one of the farms haying an area 
of 17,800 acres has been selected at a rental of 2d. per acre per annum, 
The contract price for putting down bores in the Warrego district is £1 
per foot up to 2,000 feet, including casing ; and selectors, who wish for a bore 
but are unable to pay cash, can, in most cases, make satisfactory financial 
arrangements with the boring company, and, after supplying their own grazing 
farms with water, frequently supply one or two or even three of their neighbours _ 
with bore water. The usual charge for supplying a 20,000-acre grazing farm with 
bore water is about £50 per annum, or 3d. per acre, according to circumstances. 
During the year 1898 several more bores have been put down. 
NUT-GRASS (OFPERUS ROTUNDUS). 
By PHILIP MAC MAHON, 
Curator, Botanic Gardens, Brisbane. 
Last December a gentleman engaged in horticultural work in a neighbouring 
town visited the Botanic Gardens. ‘This is the time of year when, as is well 
known, nut-grass is at its best—or worst. As a result of his visit he wrote this 
letter : “ Dear Sir—In walking through your Gardens the other day 1 was 
surprised to see so little nut-grass, as I recollect the place much overrun with it. 
Kindly let me know how you keep it down, and how I can get rid of a large 
patch of it? Would salt kill it ? I am told buffalo-grass would smother it, 
but ina garden the remedy would be worse than the disease, I fear. T have dug 
and ploughed up the plot, and am now picking it out by hand, but it is slow and 
costly work.” 
At the Agricultural Conference recently held in Mackay, the subject of 
the eradication of nut-grass was one of those discussed, and the number of 
persons from yery different localities who gave their experiences in the matter
