The Anglo-Saxons commenced their career as pirates and robbers, and as pirates and robbers of the most desperate and dangerous description. In fact, the character which the Anglo-Saxons have obtained in modern times for energy and enterprise, and for desperate daring in their conflicts with foes, is no recent fame. The progenitors of the present race were celebrated every where, and every where feared and dreaded, not only in the days of Alfred, but several centuries before. All the historians of those days that speak of them at all, describe them as universally distinguished above their neighbors for their energy and vehemence of character, their mental and physical superiority, and for the wild and daring expeditions to which their spirit of enterprise and activity were continually impelling them. They built vessels, in which they boldly put forth on the waters of the German Ocean or of the Baltic Sea on excursions for conquest or plunder. Like their present posterity on the British isles and on the shores of the Atlantic, they cared not, in these voyages, whether it was summer or winter, calm or storm. In fact, they sailed often in tempests and storms by choice, so as to come upon their enemies the more unexpectedly.

Boilers Nos. 21, 22 and 23, with a few modifications, are now the standard forms. These designs are illustrated, as they are constructed to-day, on pages 48, 52, 54, 58 and 60. The last step in the development of the water-tube boiler, beyond which it seems almost impossible for science and skill to advance, consists in the making of all pressure parts of the boiler of wrought steel, including sinuous headers, cross boxes, nozzles, and the like. This construction was the result of the demands of certain Continental laws that are coming into general vogue in this country. The Babcock & Wilcox Co. have at the present time a plant producing steel forgings that have been pronounced by the _London Engineer_ to be "a perfect triumph of the forgers' art".

Properly, however, this work should be done by the assayer, if only for the following reason. It is assumed that the dry ore of the sampler and of the assayer are the same thing; according to the nature of the ore, this may or may not be the case. The assayer, however, uses the sample which he has dried for his moisture-determination, as the dry ore on which he makes his other assays, and no variation in moisture would influence the other and more important determinations. Some ores are sent to the smelter with from 5 to 15 per cent. of adherent water. In these cases it is best to spread out the sample, and taking equal portions fairly at regular intervals, weigh into a Berlin dish 20 grams. This should then be dried over a sand-bath, or if the ore is likely to be injured by excess of heat, over a water-bath until the weight is constant. The loss of weight multiplied by 5 gives the percentage of water present.
