As it was no harm had been done and, when the excitement had calmed down, and an inspection made to ascertain that the gates would now work perfectly, the tug was allowed to proceed.

"Well, what are your plans now, boys?" asked Mr. Alcando on the day after the lock accident.

"Back to Culebra Cut," answered Blake. "We have orders to get a picture of a big slide there, and we're going to do it."

"Even if you have to make the slide yourself?" asked the Spaniard with a short laugh.

"Not much!" exclaimed Blake. "I'd do a good deal to get the kind of moving pictures they want, but nothing like that. There have been some rains of late, however, and if things happen as they often have before in the Cut there may be a slide."

"Yes, they do follow rains, so I am told," went on the Spaniard. "Well, I do not wish your Canal any bad luck, but if a slide does occur I hope it will come when you can get views of it."

"In the daytime, and not at night," suggested Joe.

For several days nothing of interest occurred. Blake and Joe sent back to New York the films of the mad rush of waters through the lock, and also dispatched other views they had taken. They had gone to Culebra Cut and there tied up, waiting for a slide that might come at any time, and yet which might never occur. Naturally if the canal engineers could have had their way they would have preferred never to see another avalanche of earth descend.

Mr. Alcando had by this time proved that he could take moving pictures almost as well as could the boys. Of course this filming of nature was not all there was to the business. It was quite another matter to make views of theatrical scenes, or to film the scene of an indoor and outdoor drama.

"But I do not need any of that for my purpose," explained Mr. Alcando. "I just want to know how to get pictures that will help develope our railroad business."
