sufficiently common to yield some surplus honey, which is light 

 in color and mild in flavor. The wild cucumber, Echinocystis

 brood rearing, it is important that it be within reach at all 

 seasons, as nearly as possible. In a few localities it is never 

 sufficiently abundant throughout the breeding season for best 

 results. Fortunately, in most places, pollen is within reach 

 most of the growing months.
