M: Watch it, Mary.
W: What’s the matter?
M: This is the end of the road. There’s a river just beyond those trees.
W: Another river? I’ve never seen so many rivers anywhere in my life. Let’s go take a look.
M: This river is wide and deep.
W: Yeah, you are sure right about that. We aren’t going to be able to put any ordinary bridge across this one.
M: Do we have to get the trucks over to the other side?
W: That’s what they told me.
M: What about a ferry?
W: That’s what we’ll have to do if I can’t think of anything else, but it’ll really slow down the operation.
M: What about flying the equipment over in a helicopter?
W: We’d have to take the big trucks apart and then put them back together again. Slower than a ferry and a lot more expensive.
M: What are you going to do then?
W: Well, I’m beginning to get an idea. Have you ever heard of a pontoon bridge?
M: No. What’s that?
W: It’s a bridge that’s supported on boats. The boats are anchored at regular distances and they carry the weight of the bridge.
M: I guess that might work if you have enough boats, but won’t it take a long time to build them?
W: Maybe we can buy them.
M: Buy them?
W: From some of the native villagers. I’ve seen some fairly big rowing boats.
M: I don’t know about that. Most of those boats are pretty light.
W: Yeah, but if we tied up a bunch of them together, they might support a road. Let’s find out anyhow.
M: OK.
