good whack in the process. We resolved to do our best with this fellow 
when we had finished with the anemones. 
We tried allowing the tentacles from each of two side-by-side giganteas 
to take a firm hold on a small mojara to learn what wd uld happen. Turned

operations for awhile we went up to lunch, ^^en I returned an hour later 
the hole opening had been filled in, leaving only a tiny opening for his 
eyes to be thrust above the sand floor. But he wasn’t visible in it so I
