A good chapter is like a bad treasure map

The end of a chapter should not actually end much of anything. 

The concluding portions of a chapter ideally leave the cliff hanging and foreshadow something that will happen later.  A good rule of thumb when editing your manuscript is to read three chapters at a time, then consider whether the first of the three concludes by hinting, implying, or threatening some event that is postponed until further notice.   The succeeding chapters can either build on that unresolved question or begin a different story line while, at the same time, weaving in issues, characters, or events from the first of the three chapters.  

This is a lot like the way you feel when your puppy, or a reasonably good writing cat, comes to snuggle you --readers get a great sense of reward by picking up a character, story line, or event that was hinted at several chapters previously.  A good chapter is a lot like a bad treasure map – enough to peak interest but keep the treasure hidden a while longer.
