at the top with suitable hooks for attaching ropes for lowering. The method of using shall be to place the wooden plug in the bottom of the can and lower the can into the molasses by means of the ropes attached to the top. The gauging rod is passed through the can, releasing the wooden plug at the bottom, allowing the molasses to flow into the can to the level of the molasses in the tank. The gauging rod is then lowered through the can to the bottom of the tank and an accurate gauge of the molasses without foam is registered on the gauging rod. This procedure shall be followed both on immediate gauging as well as gauging after the lapse of the 20-day period in all cases where foam is present. No allowance shall be made for occluded air or other gases in the body of the molasses. The depth of the imported molasses having been ascertained in inches, the result will be multiplied by the number of gallons per inch in height previously ascertained when the storage tank was measured empty.

Art. 697. Gauging tank cars.-When molasses is imported in tank cars the quantity contained therein will be ascertained by gauge.

SAMPLING OF SUGARS, SIRUPS, AND MOLASSES Art. 698. General sample defined.-(a) In sampling imported raw sugars a general sample shall be taken; that is, each importation shall be sampled without regard to marks and 100 per cent of the packages shall be sampled. A separate general sample shall also be taken of (a) wet sugar, (b) damaged sugar not wet, (c) ship sweepings, (d) dock sweepings. In order to prevent any unnecessary labor and inconvenience in obtaining the sample, the inspector shall direct that the packages when discharged from the vessel upon the wharf shall be so placed that the sampler can readily obtain a 100 per cent sample. All ship and dock sweepings shall be sampled before the sampler completes his half day's work. It shall be the duty of all samplers to secure a thoroughly representative sample.

(b) In sampling separate importations of sirups or molasses placed in the same tank, care must be taken to get truly representative samples of each lot.

Art. 699. Stained bags. In the event that bags are stained from lying in storage, or from any other cause, but the sugar not damaged, the sampler in charge, as

well as all other samplers, shall exercise every precaution to see that the bags come alternately with the clean and stained sides up. When, in the opinion of the sampler in charge, the bags are not being so discharged, he shall direct the attention of the inspector to that fact, and it shall be the duty of the inspector to thereupon stop the discharge of the cargo until the instructions of the sampler are complied with. If, from any cause, in any cargo, the condition of the bags from the ground tier or any other tier shall differ markedly from the condition of the cargo as a whole. such bags shall be treated as damaged.

Art. 700. Care of samples--Letter of transmittal— Keys. (a) In the treatment of sugars under these regulations great care shall be exercised by samplers and other appraising officers to prevent the drying out of samples, as well as their absorbing moisture. A standard sugar bucket shall be used in which to collect the samples. It shall be made of heavy galvanized iron and have a height of 311⁄2 centimeters and a diameter of 18%1⁄2 centimeters. The covers of the buckets must be kept closed, except when momentarily opened to receive the sample. All the buckets containing samples from a given half day for each cargo shall be filled, with the exception of one. The label on each bucket must identify the sugar and the particular half day on which its contents were drawn and the name of the officer responsible for the sampling of same. All buckets, after being so labeled, shall be locked before leaving the spot where the samples are being drawn. The examiner or sampler in charge shall forward the samples to the appraiser's stores with a dock list on customs Form 6483-B, on which partially filled buckets shall be noted as 1⁄4, 1⁄2, or 4. After the discharge of the cargo has been completed the examiner or sampler in charge shall forward a letter of transmittal to the appraiser on customs Form 6461.

(b) The keys of the locks used on sugar buckets shall be in possession of the assistant appraiser or the examiner at the appraiser's office, who shall have sole custody of such keys.

Art. 701. Dimensions of sugar triers.-The sugar triers used shall have the following dimensions:

Art. 702. Receptacles-How sampled.-Sugar in hogsheads and other wooden packages shall be sampled by putting the long trier diagonally through the package from chime to chime, one trierful to constitute a sample, except in small lots, when an equal number of trierfuls shall be taken from each package to furnish the required amount of sugar necessary to make a sufficient sample. In the sampling of baskets, bags, seroons, and mats the short trier shall be used, care being exercised to have each sample represent the contents of the package. The greatest precaution shall be taken that the samples from each class of packages shall be kept separate and be uniform in quantity.

Art. 703. Detail of samplers.-At ports where the number of samplers employed will permit, no sampler shall be detailed in the same sugar district or on the same dock longer than one month. A complete record of the assignment of the examiners and samplers shall be kept and shall be approved by the appraiser.

Art. 704. Discharge from lighters.-Sugars conveyed on lighters from the place of original discharge before samples have been taken shall not be removed therefrom until notice of the time of their proposed removal has been given by the inspector to the examiner or sampler in charge.

Art. 705. Sampling from lighters.-In cases wnere vessels discharge in one district and the sugars are lightered to another before sampling, the manifest which accompanied the lighter and is delivered to the inspector in charge of the district where such sugars are to be weighed and sampled shall be presented to the examiner or sampler in charge for his indorsement, the same as in the case of an original permit and such manifest shall show the name of the person making entry. The inspector in charge of such district shall be held responsible for the

treatment of all such sugars under these regulations, the same as if working under the original permit.

Art. 706. Transfer of samples.-All sugar samples drawn on any given half day shall reach the examining room in the appraiser's stores not later than the close of the first official half day following, except where the place of discharge is more than 15 miles distant from the appraiser's stores. Whenever practicable the samples for each half day will be forwarded to the appraiser's stores as soon as the half day is completed. When sugars are discharged at places where the distance makes it impracticable for the regular conveyance to call for the samples, and where special provision is made by contract for other means of transportation, an official shall be detailed by the appraiser to take charge of such samples until they reach the appraiser's stores.

Art. 707. Refined sugars. In sampling receptacles containing refined sugars the percentage to be sampled shall be determined by the best judgment of the examiner or sampler in charge. Every precaution shall be taken to have the sample fairly and adequately represent the shipment.

Art. 708. Care of sampling equipment.-The utmost care must be taken to keep all the apparatus used in the process of sampling sugar clean and absolutely dry. Suitable cleaning and polishing materials shall be supplied to the samplers, who are hereby instructed to always have their implements in perfect condition. The sampler shall frequently and thoroughly clean his trier with a scraper provided for that purpose. Failure to observe these requirements shall be reported at once to the appraiser by the examiner or the sampler in charge, and such failure will be regarded as sufficient cause for suspension.

Art. 709. Sugar discharged during storm.-Sugar discharged during a rain or snow storm shall be sampled under cover. When this is impracticable, or if in the judgment of the appraiser fair samples can not be obtained by reason of the stress of weather, or for any other reason, the inspector shall immediately stop the discharge of the cargo. In the absence of the inspector the appraiser shall immediately take such steps as may be necessary to stop the discharge of the cargo.

Art. 710. Buckets for sirup and molasses samples.— The receptacle used in collecting all molasses samples

shall be the standard sugar bucket, and the regulations governing the use of this bucket in the collection of sugar shall apply with equal force when it is used for the collection of molasses.

Art. 711. Molasses and sirups-Better grades.-In sampling all grades of sirups and molasses other than blackstrap, 100 per cent of the packages shall be sampled. The contents of each receptacle shall be thoroughly stirred in order that any settlings shall be evenly distributed and the contents brought to as uniform a density as possible. Receptacles of the same size shall be sampled in groups of not more than 25, a sample of uniform quantity being drawn from each. A tally shall be kept and the label thereon shall show the number of packages which each bucket represents. The dock list accompanying the sample buckets shall convey the same information and shall account for every package of the mark. Packages of different size or character of contents, although invoiced and permitted under the same mark, shall be separately sampled, tested, and classified. If any package or packages shall, in the judgment of the sampling officer, have the appearance of sirup of cane juice, or of testing by the polariscope above 50 sugar degrees, a separate sample of same shall be taken.

Art. 712. Blackstrap molasses.-When blackstrap (frequently designated waste molasses) is imported in barrels, 10 per cent of all the receptacles shall be sampled. When, in the judgment of the examiner or sampler in charge, a greater percentage is necessary to fairly represent the importation, such additional barrels shall be sampled as, in his judgment, are necessary to secure a representative sample. Blackstrap imported in tank vessels shall be sampled as it is being pumped from the vessel. Samples of uniform quantity, in general one-half liter, shall be drawn with such frequency as to insure one sample for each 5,000 gallons.

Art. 713. Molasses in tank cars.-Molasses in tank cars shall be sampled by drawing two similar complete samples of about 1 liter each and consisting of a continuous portion or core extending from the top to the bottom of the tank. When for any reason such a core can not be obtained, the two complete samples shall each consist of three portions: One portion from the top just below the surface of the liquid, one from the center, and one from the bottom of the tank. All samples shall be forwarded to the appraiser with the least possible delay.
