This is the American black bear, who is looking so lively and seemingly inviting the young folks to have a romp, which they will be only too willing to join in. The black bear is of a timid disposition, and seldom attacks man except in self-defense. The female bear is a most affectionate mother, and many stories are related showing her care and love for her young, and her sorrow and mournful cries when any evil befalls them. On one occasion a black bear with her two cubs was pursued across the ice by some armed sailors. At first she urged her cubs to increased speed, but finding her pursuers gaining upon them, she carried, pushed, and pitched them, alternately, forward, until she effected their escape from her pursuers. |
As stated in the previous chapter, the first water-tube boiler was built by John Blakey and was patented by him in 1766. Several tubes alternately inclined at opposite angles were arranged in the furnaces, the adjacent tube ends being connected by small pipes. The first successful user of water-tube boilers, however, was James Rumsey, an American inventor, celebrated for his early experiments in steam navigation, and it is he who may be truly classed as the originator of the water-tube boiler. In 1788 he patented, in England, several forms of boilers, some of which were of the water-tube type. One had a fire box with flat top and sides, with horizontal tubes across the fire box connecting the water spaces. Another had a cylindrical fire box surrounded by an annular water space and a coiled tube was placed within the box connecting at its two ends with the water space. This was the first of the "coil boilers". Another form in the same patent was the vertical tubular boiler, practically as made at the present time. |
