The power house was to be upon virgin soil where were rocks and trees--little trees growing among rocks. In blasting and clearing the necessary place for the foundations of the building, a Robin's nest was discovered in a little tree within the space where the upheavals were to be made. When Mr. Corliss knew this he had the work transferred to the other side of the square or parallelogram around which the digging and blasting were to go, saying that it was just as well to do the other side first. But it proved that when the workmen had got clear around and back to the Robin's tree, the young birds were still not quite ready to fly. This called for a new exercise of an inventor's power of adapting means to a worthy end. Looking at the little tree with its nest and little birds high in the branches he bade the men support the tree carefully while it was sawed through the trunk a little above the ground, and then carry it in an upright position to a safe distance and stick it into the ground with proper support. The Robin family continued to thrive after this novel house-moving and all flew away together after a few more days. QUEER DOINGS OF A CRANE. A writer on "Animal Helpers and Servers" gives a remarkable account of a tame Crane, communicated by Von Seyffert. Von Seyffert had a pair of tame Cranes which soon lost all fear of man and of domestic animals, and became strongly attached to the former. Their life in a German village, in which agriculture was the sole employment and the communal system of joint herding of cattle and swine and driving them together to the common pasture prevailed, was very much to their taste. They soon knew all the inhabitants in the place and used to call regularly at the houses to be fed. Then the female died and the survivor at once took as a new friend a bull. He stood by the bull in the stall and kept the flies off him, screamed when he roared, danced before him and followed him out with the herd. In this association the Crane learned the duties of cowherd, so that one evening he brought home the whole of the village herd of heifers unaided and drove them into the stable. From that time the Crane undertook so many duties that he was busy from dawn till night. He acted as policeman among the poultry, stopping all fights and disorder. He stood by a horse when left in a cart and prevented it from moving by pecking its nose and screaming. A Turkey and a Game Cock were found fighting, whereon the Crane first fought the Turkey, then sought out and thrashed the cock. Meantime it herded the cattle, not always with complete success. The bovines were collected in the morning by the sound of a horn and some would lag behind. On one occasion the Crane went back, drove up some lagging heifers through the street and then frightened them so much that they broke away and ran two miles in the wrong direction. The bird could not bring them back, but drove them into a field, where it guarded them until they were fetched.
