The flood was not clear, and caught around the fins of the ship were huge loops of weed. Some variety of fish had been beached close to the foot of the ramp, and a scaled tail beat waves as the stranded monster fought for life. Other debris showed tantalizingly now and again as the water was sullenly sucked away from the sand.

“What the-I” Cully’s start was near to a jump. Over-over to the right! What is that?”

Something was venturing out on the still-wet sand, following the retreating line of the sea. But, what it was, none of them dared guess. Kimber ran back into the ship while the rest tried vainly to see it better. The color was queer, a pale green, hardly to be distinguished from the sea water as it scurried along on four thin legs. But the outline of its head!

“Here!” Kimber skidded down the ramp, keeping himself out of the sea by a quick grab for the rail. He carried a pair of field glasses. “Is it still there-yes, I see it!” He focused the lenses in the right direction. “Great guns!”

“What is it?” demanded Rogan, plainly doing his best to keep from snatching the glasses away from the pilot.

“Yeah,” Cully, too, was shaken out of his usual calm, “pass those along, fella! We all want a look-see!”

Dard squinted, trying to make natural sight serve as well as the lenses Kimber was now passing to Rogan. At least the thing on the sand did not appear to be alarmed either by the ship or the men watching it. Maybe it would stay in sight until he, as the very junior member of the party, had the right to use the lenses too.

It stayed, digging in the wet sand, until Cully did pass the glasses. Dard adjusted them feverishly. Having met the fungi spiders and a flying dragon, he could hardly be surprised by the weird beast he saw now. Its pale green skin was entirely hairless, nor was that skin scaled-instead it resembled to a marked degree his own smooth flesh. The creature’s head was pear-shaped with ears which were hardly more than holes and large eyes set far apart so that the range of vision was probably wider than that of any Terran animal. But that pear head ended in what could only be described as a broad, duck’s bill or hard blackish substance. And just as Dard trained the glasses upon it, it folded its hind legs neatly under it, to sit up in a doglike stance and gaze mildly across the dwindling tongue of sea straight at the star ship. Sand clung to its bill and it absent-mindedly brushed that off with a foreleg.

“Duck- dog,” Kimber named it. “Doesn’t look dangerous, does it? I’ll be-! Just look at that!”

“ ’That’ was a short procession of more duck-dogs emerging from a dark crevice in the cliff to join the first. One of them, about three-quarters the size of the first, was the same pale green, but the three others were yellow, the exact yellow, Dart noted, of the strata in the diff. In fact, as they marched by a projection of that particular stratum, they faded from sight. Two of the yellow beasts were full grown but the third was very small. And halfway along the path it sat down, refusing to move on until one of the larger animals returned to butt it ahead.
