"Supposing I hunt for the trail while you look for Si? It won't take all three of us to look for the boy."
The others were willing, and soon Mark and Bob were on their way down the mountain, following the direction the slide had taken. The way was rough and uncertain. Trees often barred their progress, and they had to pick their way around loose rocks with care.
"Take care that you don't take a tumble," cautioned the former sailor boy. "We can't afford it."
A tree was in front of them and they were on the point of going around it when they heard a faint cry. There lay poor Si, caught fast between two heavy branches.
"Oh, I was afraid you were all dead!" said the former farm lad. "Didn't the landslide cover you up?"
"Yes, but we dug our way out," answered Mark. "Are you hurt?"
"I think my shoulder is bruised, that is all. But the shock stunned me and I only came to my senses a little while ago. Can you get me out of this trap?"
"To be sure we can," cried Bob, and he and Mark set to work immediately. It was no easy task, but was finally accomplished, much to Si's satisfaction.
"By the way, I saw those Mexicans again," said Si, as he nursed his bruised shoulder. "I caught sight of 'em just before the landslide came. They were near the top of the mountain."
"My gracious, I wonder if they started that landslide!" gasped Mark.
