Of course it was not all done at once , for the seals are not very clever , and they need a long time to turn things over in their minds , but year after year more seals went away from Novastoshnah , and Lukannon , and the other nurseries , to the quiet , sheltered beaches where Kotick sits all the summer through , getting bigger and fatter and stronger each year , while the holluschickie play around him , in that sea where no man comes .
