name of the vessel and date of arrival, the number of wine gallons, and in the case of spirits also that of proof gallons, contained in the package, and the commercial name of the wine or liquor contained therein; and the stamp will be signed by the gauger who will inspect the package.

ART. 1683. Before the removal from the custody of the customs of any package of imported spirits, wines, or malt liquors, the gauger will make a careful gauge of the package, and will cut upon the bung stave, or on staves adjoining the bung stave, when the latter is covered with old marks, the number of wine gallons, and, in the case of spirits, the proof, outage, and the number of proof gallons, and will also cut or mark upon the head of the package, in letters at least one-half inch in length, the date of inspection, the serial number of the stamp affixed, and the name of the spirits, wines, or malt liquors contained therein as known to the trade. At the close of each month the stubs will be compared with the report of the gauger by an officer to be designated by the surveyor, or at a port where there is no surveyor, by the collector, and when all the stamps have been used the book of stubs will be filed in the collector's office with the certificate of the proper officer attached that the stubs therein have been examined and found to agree with the stamps used, as per gauger’s report.

ART. 1684. The gauger will affix the stamps, and in attaching them will take care to guard against their cracking and peeling off. Collectors of customs will be guided by their own judgment in regard to requiring the goods to be carted to public store or bonded warehouse for the mere purposes of inspection and stamping, and where, in their judgment, such inspection, stamping, etc., can as well be done at the place of landing, they may permit that course to be taken. Each stamp must be tacked with eight tacks, and immediately upon affixing, canceled by means of a suitable stencil plate having five parallel waved lines, which must be long enough to extend 1 inch beyond each end of the stamp on the wood of the cask. A coating of transparent varnish or other suitable substance should be applied to protect and preserve the stamp after it has been affixed and canceled.

ART. 1685. The proof of liquors will be ascertained by Tagliabue's hydrometer, by which the percentage of proof spirits is indicated by 100 degrees, and the notations of proof shall conform to the scale of that hydrometer, as explained and corrected in Tagliabue's manual for gaugers.

ART. 1686. Gaugers will keep an exact account of the time that temporary assistants and laborers are employed, and make a weekly pay roll, in duplicate, of such service.

§ 7. MARBLE MEASURERS.

ART. 1687. Marble must be actually and carefully measured, so as to ascertain the exact quantities landed, whenever duties are to be assessed thereon.

Measurers of marble are required to measure all marble landed from a vessel from a foreign port or place. Having measured the marble described in any order or permit, or landed as aforesaid, they will keep a correct record thereof, and of each block or piece measured, which record or book shall be indorsed with the name of the vessel from which the same was landed, the place whence imported, and the name of the importer, and be filed in the surveyor's office. Measurers will also make out two returns of the said measurements and certify to the same, and promptly deliver them to the collector.

ART. 1688. In measuring marble blocks for the purpose of ascertaining the dutiable quantity thereof, three-fourths of an inch on each surface may be allowed in accordance with the usual custom, on account of the indentations made by the quarrymen in shaping the blocks.

When one or more of said surfaces has been sawn, and the surface is level, and not injured or defaced, but half an inch allowance will be made.

If injured by blows, or in any other manner, deductions in the measurement may be made for such defects.

When corners are off blocks, or there are other defects running deeper than three-fourths of an inch, a sufficient allowance will be made from one end of the block to so level it as to make it equivalent to a parallelopiped. This allowance must not be made to the depth of the defect; on the contrary, 1, 2, or 3 inches will usually compensate for a broken corner a foot or more in depth.

When the corner is off in such a manner that the defect extends the entire length of the block, the allowance must be made from the side and not the end. If the block is substantially in one of the forms here represented, the correctness of the measurer's estimate can be proved by dividing the block into two parts, measuring each separately and adding together the results. It is the duty of a measurer to so carefully examine every part of every block as to make the nearest possible approximation to the dutiable quantity. The measuring rod should be

applied to the middle of both sides to get the length, and the middle of both ends to get the breadth. In taking the thickness still more care is required, and it is well to apply the rod to three or four places on each side and twice to each end.

§ 8. STANDARD GAUGE FOR IMPORTED SHEET AND PLATE

IRON AND STEEL.

ART. 1689. The act of Congress entitled "An act establishing a standard gauge for sheet and plate iron and steel," approved March 3, 1893, prescribes as follows, viz:

That for the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the United States of America, namely:

And on and after July first, eighteen hundred and ninety-three, the same and no other shall be used in determining duties and taxes

levied by the United States of America on sheet and plate iron and steel. But this act shall not be construed to increase duties upon any articles which may be imported.

SEC. 2. That the Secretary of the Treasury is authorized and required to prepare suitable standards in accordance herewith.

SEC. 3. That in the practical use and application of the standard gauge hereby established a variation of two and one-half per cent either way may be allowed.

ART. 1690. In accordance with the requirement of section 2 of said act, and on the recommendation of the Superintendent of the Coast and Geodetic Survey, standard gauges have been procured and tested, which have been furnished by the Department to the appraisers at the principal ports, viz: New York, Boston, Philadelphia, Baltimore, New Orleans, San Francisco, Chicago, St. Louis, Cincinnati, Cleveland, Portland, Me., Portland, Oreg., Savannah, and Charleston.

1. The use of said gauge shall be restricted to the gauging of sheet and plate iron and steel, as prescribed by said act, and the present custom of gauging wire by the Birmingham gauge will be continued.

2. In determining the gauge of sheets and plates the approximate thickness in fractions of an inch or in millimeters should be made use of, and, in case of appeal, reference will be had to the weight per unit of area in determining the question.

3. The following directions will be observed in the use of the standard gauge, viz:

The pitch of the screw is 0.5 millimeter. The graduation on the hub, in a line parallel to the axis of the screw, is in millimeters, and is figured 0, 5, 10, 15, etc., every fifth division. As the pitch of the screw is only 0.5 millimeter, two complete revolutions are necessary to open the caliper 1 millimeter. The beveled edge of the thimble is graduated into fifty parts, and is also figured 0, 5, 10, 15, etc., every fifth division. Each division, when passing the line of graduation on the hub, indicates that the screw has made one-fiftieth of a turn and the opening of the caliper increased one-fiftieth of 0.5 millimeter or onehundredth of a millimeter.

4. Hence, to read the caliper, add to the number of millimeters visible on the scale of the hub the number of division on the scale of the thimble from zero to the line coincident with the line of graduation on the hub, care being taken to note whether the thimble has made a complete revolution or not since registering the last number of whole millimeters; if it has, Q.5 millimeter must also be added.

5. In addition to the regular graduation on the hub, there are three extra marks thus, T, one to the left the others to the right of the regular graduation. They are marked 10, 20, and 25, and correspond to these numbers in the new gauge adopted by Congress March 3, 1893. To set to these numbers it is only necessary to make the beveled edge of the thimble tangent to the crossing of the two lines, and the zero line of the thimble coincident with the line of the T, parallel to the axis of the screw.

6. Constant use will cause some slight wear on the gauge screw and on surfaces brought in contact with objects measured. To compensate for wear of the screw there is a taper nut on the hub, which, when turned, contracts the hub and causes the screw to be held more tightly. In making this adjustment the sleeve should be withdrawn only just far enough to use the small wrench furnished with the caliper.

7. Should the zero of the thimble not coincide with the zero line on the hub when screwed up with gentle force, the thimble should then be turned until the zero points on the two scales coincide, and the stationary measuring surface adjusted by means of a screw-driver until the two surfaces are in contact. This adjustment will be necessary at intervals, owing to the wearing of the measuring surfaces.

§ 9. MEASURERS OF VESSELS.

ART. 1691. Inspectors acting as measurers are to perAct June 26, form their duties in the manner prescribed by articles 74 to 91 of these regulations. They will obtain from the surveyors ordering the measurements a statement of the name, nationality, and location of each vessel to be admeasured, and in every case the admeasurement must be made by at least two inspectors in company. Where an admeasured vessel is a new American vessel, the inspectors will ascertain if her name and home port are painted on the stern.

The original measurements and computations will be entered in permanent record books, from which certificates. of admeasurements may be issued. Where doubts exist as to whether foreign vessels have been admeasured, inspectors should visit such vessels, by authority from surveyors, and ascertain and report the facts.

ART. 1692. Inspectors designated to examine and admeasure passenger vessels from foreign ports are required,
