For sugar alone the cost has been from £6 to £7 7s. The majority of the 
estates are small, the average area under cane being only 178 acres. The 
annual production of rum is a little over 2,000,000 gallons. 
There are 6,000 small mills, probably cattle mills, owned by the peasantry. 
Cane farming as carried on in “Trinidad does not appear to have been tried on 
any appreciable scale in Jamaica. 
BRITISH GUIANA. 
The area under sugar in this colony is given as 66,908 acres, divided amongst 
64 proprietors. The amount of capital invested is £10,000,000, and the export 
of sugar in 1895-96 was 101,160 tons, of the value of 1,046,160. Theayerage 
yield per acre only reaches 1°5 tons of sugar. Sugar is the staple production 
of British Guiana, and it i8 carried on with considerable energy and 
intelligence. At one time, the cost of production was £16 1s. 7d. per ton. 
Now the cost has fallen to £9 10s. ; 
All the mills are of modern style and fitted with double and triple crushing 
machinery with or without maceration, and in two factories the diffusion 
process is employed. As much as 90 per cent. of juice is extracted by triple 
crushing (with 10 per cent. dilution), and from this is recovered 84 to 88 per 
cent. of marketable sugar, polarising on the average about 95 degrees. The 
ayerage return of sugar obtainable all over the colony is placed by Professor 
Harrison at about 9 per cent. of the weight of cane.

TEXAS FEVER PROBLEMS. 
Tw this number of the Journal we conclude the very interesting articles on 
Texas Fever by Dr. E. Salmon, D.V.M., Department of Agriculture, 
Washington (U.S.A.). 
Mr. P. K. Gordon, Chief Inspector of Stock, Queensland, writing on the 
subject of these articles, considers that their publication will be productive of 
much good, “if only to show our cattle-owners that our investigations are on 
the right track.” 
Referring to dipping, he says :— 
“When cattle can be put into railway trucks and sent away immediately 
after dipping, there would be no risk in thus permitting dipped ticked cattle 
to travel to clean country (assuming an effective dip to have been discovered), 
but it would be impossible to truck cattle immediately from the dip here. I still 
think, however, that dipping will ultimately play an important part. in 
mitigating the pest, and, therefore, all information collected on the subject: 
should be given publicity to.” 
TEXAS FEVER PROBLEMS.—IV. : 
It has been shown in previous articles that the problem as to how cattle 
from the infected district may be moved to other sections of the country 
without endangering the stock of the localities to which they are taken is 
solved by a method of dipping the infectious cattle which kills all of the ticks 
on them. ‘The progress made in perfecting this method has been briefly out- 
lined. The second problem, or how to take cattle from the non-infected parts 
of the country into the infected district without subjecting them to the great 
danger of contracting the disease and dying from it, is of an entirely different
