LIQUIDS BY PARCEL POST.
The Postmaster General has announced the following amendment, covering the mailing of liquids by parcel post:
Sec. 22. Admissible liquids and oils, pastes, salves, or other articles easily liquefiable, will be accepted for mailing regardless of distance when they conform to the following conditions.
2. When in strong glass bottles holding four ounces or less, the total quantity sent in one parcel shall not exceed twenty-four ounces, liquid measure. Each bottle shall be wrapped in paper or other absorbent substance and placed in a box made of cardboard or other suitable material and then placed in a box and packed in a container made of double-faced corrugated pasteboard of good quality. The corners of the container must fit tightly and be reinforced with tape so as to prevent the escape of any liquid if the contents should be broken, and the whole parcel shall be securely wrapped with strong paper and tied with twine. Single bottles of liquid holding four ounces or less may also be packed as prescribed in the following paragraph:
3. When in glass bottles holding more than four ounces, the total quantity sent in one parcel shall not exceed sixteen ounces liquid measure. The bottle must be very strong and must be inclosed in a block or tube of metal, wood, papier mache, or similar material; and there must be provided between the bottle and the block or tube a cushion of cotton, felt or other absorbent. The block or tube must be at least five thirty-seconds of an inch thick in its thinnest part for bottles holding eight ounces or less, and at least three-sixteenths of an inch for bottles holding more than eight ounces. The block or tube must be rendered water-tight by an application on the inside of paraffin or other suitable substances and must be closed by a screw-top cover with sufficient screw threads to require at least one and one-half complete turns before it will come off. The cover must be provided with a washer so that no liquid will escape if the bottle should be broken.
4. When in a metal container, the weight of the parcel must not exceed eleven pounds. The container must be hermetically sealed, inclosed in a strong box and securely wrapped.
5. All packages containing liquid must be marked “FRAGILE.”
