TICKS. Among vegetable productions what is known as Beggar ticks are the ripe seeds of Bidens ehrysanthemoides, and also the seeds of Spanish Needle, B. bipinnatus, is sometimes so called. Sheep ticks, Hippoboaca mina, is a small louse fly, without wings, often exceedingly troublesome, especially to lambs, the insect leaving the mother sheep for the lambs, while sucking. All sheep should be examined occasionally for ticks. When not numerous they may be removed by picking. They may be destroyed by dipping the sheep (with the exception of the face and head) in a mixture of arsenic, soft soap, potash, and water, or other arsenical preparations; but they, being highly poisonous, are very unsafe remedies, and can not be recommended for general use. Decoctions of tobacco, applications of brimstone, lard, paraffine oil, etc., about the neck, are common remedies. Snuff or sulphur in powder,, rubbed thoroughly into the wool, is sometimes used with good results, and a bath made by steeping tobacco in water, about two pounds to ten gallons of water, in which the lambs are immersed, (except the face,) is said to be effec tive, but in some cases has proved injurious to the health of the lambs. In the case of lambs, therefore, it would be proper to reduce the strength. It should, however, be observed that the weakness produced by the tobacco most usually passes off in a short time. Of Cattle
ticks, one of those most usually found is the common Irodes, and which at one time was popularly supposed to be the cause of the Spanish fever in cattle. They are not common in the north except when distributed by Texan cattle, which often are covered with them, when driven from the south. The remedy is by pick ing. The late lamented Dr. Walsh, in referring to these insects, gave the probable facts in the case as follows: There is a prevailing opinion amongst certain classes, that the ticks which are found on the cattle which die of Texas fever are actually the cause of the disease. In view of this fact, specimens of these ticks have been sent his for examination, from different localities in Illinois, and they are identical with those we have ourselves examined upon diseased cattle in St. Louis, and are but the common cattle tick. It is exceedingly improbable that they have anything to do with the disease, although it is barely possible that they may communicate the infection from the Texas cattle to our native herds.
