USTAVUS LINDENTHAL, who is connected with much monumental constructive work in and around New York City, is a man of large ideas and tremendous energy. Two enormous steel structures, now in the course of completion, span the adjacent waters of New York and will go down to time as the work of his brain. Tens of thousands of passengers crossing the ferry from Manhattan to Long Island City daily, view with curious interest the enormous superstructure of steel that stretches across Blackwell's Island and in the mist and fog seems to swing in the air unsupported. This huge piece of engineering is part of the Blackwell's Island bridge and projecting arms. reaching out across the East river from each shore towards the central span. The bridge will be two miles in length, and will cost over $20,000,000. It will carry four elevated tracks, four trolley tracks and have a roadway and a promenade. At Hell Gate, through which is

the entrance to New York harbor from Long Island Sound, Mr. Lindenthal is constructing another monumental work, almost as ambitious as the first. The Hell Gate bridge will carry the heaviest loads of any bridge in the world.

It was Lindenthal who originated the Hudson river bridge project, a scheme to throw a colossal suspension bridge. across the Hudson, the span of which was to be three thousand feet; the height of the towers sustaining the spans to be three hundred feet; the cost to be $80,000,000. This is the big dream of the Austrian bridge builder, but so peculiar are the laws of New York and New Jersey that it is probable that it may never be realized unless private enterprises make it possible. Mr. Lindenthal came to this country from Braunn, Austria, in 1876. Though equipped with large experience as a bridge and railroad. builder he was determined to become an American and threw off his coat and went to work as a carpenter and as a mason until he found the opportunity to pursue his profession in a manner better suited to his training and his desires.

T Stellingen, a pretty suburb of the port of Hamburg, there has recently been completed one of the finest zoological gardens existing in Europe, if not in the world.

The zoological park occupies thirty-six acres of ground and arrangements have been made so as to throw another twenty-six acres into the park if desirable. But it is the bold and even daring manner in which it is being laid out that calls for special attention. Here you can gaze at lions, tigers, and other wild beasts appearing to the naked eye to be entirely in the open, no iron bars or netting interfering with your view.

A description of the lions' quarters will give an idea of how this is being

accomplished. At the back of the lion' house, which is artistically covered all over with imitated rockwork, there is a space sixty feet wide by forty-five feet deep. On three sides there are rocks which rise to such a height that no animal could possibly jump over them, while they are too steep to be climbed. The other side is absolutely open, but the animals are securely confined to their inclosure by means of a broad ditch, fifteen feet deep and half full of water. Immediately in front of this ditch is a narrow strip of garden full of tropical ferns, plants, and other shrubs, and then comes the public footpath. From the latter the public gaze at both lions and tigers, nothing separating them but the ditch. From the animals' side of the ditch to the footpath there is a distance of thirty feet. No animal could leap this,

for the inclosure is so designed that it is impossible for the animals to take a running jump in that direction.

Eight lions and three Bengal tigers now occupy this inclosure.

It is only right to add, perhaps, that all these beasts are tamed animals; that is to say, they are accustomed to the presence of their keeper, who can move freely in and out among them. Should an animal by any chance fall into the ravine, it can regain its den by a series of inverted steps at one end of the ditch. Another interesting sight in this novel zoo is the artificial mountain where ibex, mountain sheep, goats, and deer disport themselves. These mountains are virtu

and large pieces of granite stones have been put into the cement, to afford the animals a firm foothold in climbing during frosty weather.

The garden really consists of four distinct sections. The first of these is devoted to all kinds of aquatic birds. The second section is replete with camels, dromedaries, yaks, llamas, ostriches, etc. The third section is the open-air lion inclosure for the big 'cats. The last section is the artificial mountains. On the top of the latter are placed large eagles and vultures, and these birds are moving apparently at liberty, being only fastened by thin chains. Standing, therefore, in front of the first section, namely, the lake

ally masses of imitation rocks, piled one on top of the other. In all there are some eight of these mountains, and they tower in height from sixty to one hundred and fifty feet.

To watch the ibex climb the steep sides and jump from one precipice to another is a fascinating spectacle. A framework of timber and poles was built on pillars of brickwork. The whole structure was then covered with a layer of thick cement. The rocks are so arranged that the animals can climb to the highest points. To prevent their slipping, small

upon which is placed the waterfowl, the visitor is confronted by a wonderful panoramic view of wild animal life, for he is able to see at one time the whole of the four sections and the animals confined within them, some six hundred birds and mammals in all. This vast collection of animals appears to be able to roam about of their own free will, for the visitor is unable to detect the ditches and other cunningly devised arrangements that are confining the animals to their allotted inclosures.

The whole idea of the proprietor of the
