When an assay is required of a quantity of ore made up of parcels of different weight and quality, each parcel should be separately sampled and parts of each sample, bearing to each other the same proportion by weight as the original parcels, should be taken and mixed. For example, a lot of ore is made up of one parcel of A, 570 tons, one of B, 180 tons, and another of C, 50 tons; a sample representing the whole may be got by mixing 57 parts of a sample of A with 18 parts of a sample of B, and 5 parts of a sample of C. A bruising plate, like that in fig. 2, is convenient for general office work. The slab is of cast iron, about an inch thick. It is firmly supported on a solid block of wood, and pivoted for convenience in emptying. The bruising-hammer is steel-faced, about 4 inches square, and 1-1/2 inch thick. The block is firmly fixed to a small table or tressel, so that the slab is about 2 feet 6 inches from the ground. The slab is cleaned, and the sample collected with the help of a stiff-haired brush. ~Drying: Determination of Moisture.~--In practice, the moisture is generally determined by the samplers, and the proportion is specified in grains per pound on the label attached to the sample when it reaches the assay office. The method adopted is usually to dry 1 lb. = 7000 grs. of the ore in a frying-pan heated over a gas flame, or in an ordinary oven, until a cold bright piece of metal or glass is no longer damped when held over it. The loss of weight in grains = moisture. |
The most important spoon in the Jamestown collection, and one of the most significant objects excavated, is an incomplete pewter spoon--a variant of the trifid, or split-end, type common during the 1650-90 period. Impressed on the handle (in the trefoil finial of the stem) is the mark of the maker, giving his name, the Virginia town where he worked, and the year he started business. This is the sole surviving "touch" or mark of an American pewterer of the 17th century. The complete legend, encircling a heart, reads: "IOSEPH COPELAND/1675/CHUCKATUCK." (Chuckatuck is a small Virginia village in Nansemond County, about 30 miles southeast of Jamestown.) Joseph Copeland later moved to Jamestown where he was caretaker of the statehouse from 1688-91. He may have made pewter in Virginia's first capital. His matchless spoon found in the old Jamestown soil is the oldest dated piece of American-made pewter in existence. |

And on January 5, 1066, King Edward, the son of Ethelred, died. On the morning of the day following his death, the body of the Confessor was laid in the tomb, in his new church; and on the same day--HAROLD WAS CROWNED KING in his stead. Thus three very important events--the consecration of Westminster Abbey, the death of Edward the Confessor, and the crowning of Harold--all occurred during the same Christmas festival. | ||
