And some fell on stony ground
 The word was preached to some persons who had hearts of stone, and which remained so: 
 where it had not much earth;
 and so could be received only in a notional and superficial way, but could take no place, so as to produce any good effect: 
 and immediately it sprung up;
 a sudden and hasty profession of the word was made, without a powerful experience of it: 
 because it had no depth of earth;
 if it had, it would have been longer in coming up; more work would have been done by it, which would have required more time, before a profession of it had been made.
