CHANGE IN CATTLE QUAR-
 ANYTIME REGULATIONS
Arsenical Solution As We'll as Crude Petroleum to be Employed for Dip ping Cattle for Destruction
 of Ticks.

The Department of Agriculture will soon issue new regulations governing the movement of cattle from the area under quarantine on account of Texas or tick fever. These regulations will become effective about April l, and will permit the movement of cattle from the quarantined area provided they are properly dipped under gov ernment supervision. The new reg citations differ from those hitherto in effect in that they provide for the em- ployment of an arsenical dipping fluid as well as for crude petroleum which has heretofore been used for the destruction of the ticks that transmit the disease. Experiments by the Bureau of Animal Industry in dip- ping cattle in an arsenical solution indicate that this method of treat ment Is sufficiently effective to be permitted for cattle intended for in- terstate movement for purposes other than immediate slaughter.
 The vats in which such dipping is done under supervision shall be ap- proved by the Department; they shall have, at their maximum working ca pacity, length of not less than 40 feet at the dip line, a width of 34 to 40 inches, and minimum depth of swim of 5 1-2 feet; the sides shall be perpendicular instead of sloping, the only slope below the dip line being that at the end from which the cattle leave the vat. The slide board shall be to 1-2 feet long with slope of not less than 45 degrees. Vats that are already installed, which have a length of not less than 35 feet at the dip line, otherwise conforming to the above requirements, except that they may have sloping sides, may be approved, provided, of course, that they were we'll constructed, water tight, and in general good condition. The vats shall be covered when not in use; shall be so constructed that water from rains and overflow can- not run into them, and that the drainage into the vast from the drainage pens shall be cut off when they are not in use.
 In order that the dipping of cattle may be facilitated, the Department of Agriculture desires to secure imme- diately the names of manufacturers who can furnish to cattle owners or others interested a standard grade of white arsenic which must be finely powdered and guaranteed to be at least 99 per cent pure. The Depart ment wishes the manufacturer to place upon packages intended for use in dipping statement guaranteeing that the arsenic conforms to the standard of purity indicated. Com munications on this subject should be addressed to the Chief of the Bureau of Animal Industry, Department of Agriculture, Washington, ID. c. Copies Ol lAC ACM Auol oAtAhO lSSuAolioAAoj when issued may be obtained on ap- plication to the Bureau.
 The territory under quarantine for Texas fever embraces the whole states of Louisiana, Alabama, and Florida and parts of California, Tex as, Oklahoma, Missouri, Arkansas, Tennessee, Mississippi, Georgia, South Carolina, North Carolina and Virginia. The area under quarantine has been reduced by more than S0, 900 square miles within the last three years as result of the campaign be- ing waged by the Federal and State authorities for the extermination of the ticks, and as this work progresses the quarantine will be removed from additional territory.
