Texan Cattle Fever. This disorder, which was formerly very troublesome and fatal, at certain times in the year, to Northern cattle, which had mingled with those coming from our Southern States, or were put into cars, stock yards, or pastures recently occupied by them, has now become almost a thing of the past, owing to the well directed efforts of the Department of Agriculture, at Washington, to prevent such mingling. It is communicated to Northern cattle by a tick which, living upon the Southern animal, is, by cohabitation or otherwise, transferred to the Northerner, through the skin of which he inoculates the peculiar poison. Cattle born and raised in the South are not affected by the poison which, although apparently constantly present in their blood, does not seem to exert, as a rule, any markedly bad effect upon them. Formerly, all of the cattle taken from the North into the "tick belt " died, with very few exceptions. It has now been found that such animals can be taken South and remain unaffected, if certain very simple measures are taken and the Northern animals are not allowed to mingle with the natives. If an animal is to be taken South, it receives a thorough coat of any good greasy "slush," as for instance that used by railroads, over the entire body; upon arrival at its destination it is driven into a well fenced pasture, where no natives are kept and which is free from low bushes or trees with low branches. If she is to be put into a barn or cowshed, the building must be new or one that has not previously been occupied by Southern cattle; it need not necessarily be more than a simple shed, but should be set up on low posts. The first coating of slush may be allowed to wear off when, if the above directions are fully carried out, it only will be necessary in future to slush them up to the knees and hocks occasionally, which will be sufficient to prevent the ticks being able to gain any lodgment on the animal. Cattle treated in this way do not become immune, and, therefore, must not be allowed to mix with the native animals at any time.
