Inoculation, for Pleuro.

Writing to a friend in, Scotland, Mr Walter Gamson, Norley;.Thargomindale, an Australian stockowner, . gives the following account of his experience of pleuro and inoculation:—Pleuro broke out here very suddenly in ,1886, .owing, I believe, to infection got from travelling cattle, as a good many of the stores were full of it. After losing over 1Q0& head I set to work to inoculate, and stopped it - almost immediately. We put 1 through some 29,000 in a month sinice I. have inoculated my "weaners," until lately, when the supply of virus failed. However, I have sent to Brisbane to get. the prepared virus, and if it acts<l will let you. know,, The plan we '- take is, when the beast is at the proper stage shoot him in the head 1." If you fire behind tJie^fchpulder the blood will get mixed with the virus, making it useless. The animal must be bled well, as if it were for beef. Cut the hide; from the second to the "fifth *ffo and skin quite close to the ribs, then cut and throw back the second, third, fourth, and fifth -nbs, : and -you- have the lungs exposed. If the- beast is at the proper stage the'; lung will be streaked all over, with a light yellow fluid, the color of sherry or salad oil. You will also find this liquid round the lung, and probably, some sticking to the ribs, congealed, but which becomes liquid when shaken in a bottle, and does not congeal again. Cut the lung in"' thin slices into some. vessel, af terwards^put the slices into fine muslin or calico'and squeeze the remaining virus , the: liquid* from round the lung and on the ribs,as well. ,-After it has been well strained it''is reaiiy for use. Should you wish to" keep .some part of the fluid, strain through rough powdered charcoal, afterwards passing it/ through muslin. But - the' bottles, used J to store it must be' perfectly clean. Use "'black bottles,. with stoppers, to exclude.light as well as air, if' f possible^ We bury it, but . I can't say .it . keeps well here. >. In applying; the matter, we use both the. seton and; the knife. I prefer the former. 'f With unskilled hands it is much safer. -We use an inoculating needle with either worsted or , twine soaked in virus and passed into theouter side of the tail, abbut:2£ to 13 inches from point, taking care to drawv blood. The whole thing is very simple,- but cattleoperated upon require watching, as occasionally the tails require cutting off;-; If the virus prepared in Brisbane acts, 1 *I will have every calf branded and inoculated. I have now 32,000 head of cattle* here and not a sign of pleuro in the herd, 1 so I have substantial cause to believe in inoculation, though some cattlemen tell you it is no use. I have done it "ever since I began to work amongst cattle, and always found it act beneficially.
