Water, The rapids don't run very far, averaging about 350 

 feet at that point. You just see part of the Falls from that end. 

 This is the Rainbow Falls, which you remember I showed 

 you on the map. At the time we were there the water was 

 very low, but still the Rainbow Fall had its rainbow, and 

 there you have sunshine all day long. This is the great 

 abyss into which the water plunges. The streams are coming 

 from away down in the Basaltic rock. This is the Main 

 Falls. It is not a continuous stretch of water. It is unlike 

 Niagara in this respect. Here you have it broken, but this is 

 the Main Fall. I estimated that the volume of water would 

 be about one-fifth of that of Niagara, but there are times 

 when there is much more water. You must think of this as 

 being more than twice as high as Niagara and the mist keeps 

 everything moist around it. There are hundreds of acres of 

 forest kept fresh and green from the spray of the Falls. This 

 was the one thing that really satisfied you in the way of a 

 tropical forest. 



Here you have that immense can5^on, more than 400 feet 

 deep. Here is the bridge across the river. We are proud of 

 our steel arches. The steel bridges are certainly beautiful at 

 Niagara, but here is a steel bridge that is very much longer 

 and very much higher. You have a bridge more than 600 

 feet long in a single span, more than 400 feet above the water, 

 one of the most impressive things that we encountered. 



While completing this bridge, when they got to the 

 middle strand, they had them brought out and placed, and 

 were horror-struck to find that it did not fit. Then it 

 occurred to someone that when the hot sun was gone, it 

 would cool down. Then it just fitted and they put it into 

 place. Their measurements were a little out. The cold 

 night had contracted the steel enough so that it fitted into 

 place perfectly. We were there just in time to open the 

 bridge. At present the railroad is two or three hundred 

 miles away from the bridge. We were there when the first 

 passenger trains were beginning to cross. 



Here is a view from the bridge down the stream, down
