For example: it is not everywhere that there is plenty of pitsand, rubble, fir, clear fir, and marble... Where there is no pitsand, we must use the kinds washed up by rivers or by the sea... and other problems we must solve in similar ways.

Context: If there are no sandpits from which it can be dug, then we must sift it out from river beds or from gravel or even from the sea beach.
