SUMMARY OF MORE IMPORTANT CONCLUSIONS. 



1. Bees use freely the wax in foundation to extend both the 

 midrib and the cell walls of honey comb. 



2. The heavier the foundation used, the heavier, as a rule, 

 will be the comb built upon it. 



3. If the midrib of a foundation is much lighter than that ot 

 natural comb, the bees are likely to strengthen it by adding wax to 

 the bottom of the cells.* 



4. If the midrib of the foundation is thicker than the mid- 

 rib of natural comb, it will result in a comb with a midrib thicker 

 than the natural. Or, to state it diflferently, the bees will not thin 

 the midrib of a foundation down to the thickness of worker comb 



■ built in the natural way. 



5. Midribs of foundation that are not more than .17 of a 

 millimeter (.007 inch) in thickness, are thinned little or none by the 

 bees. 



6. Drone comb has a thicker midrib and heavier cell walls 

 than worker comb. 



7. A foundation with a heavy midrib and very slight cell 

 walls, will still produce a comb with lieavy cell walls. 



8. Very high cell walls in foundation are not cut down to 

 the thinness of cell walls in natural comb. 



9. The thin and extra thin and the "1899" deep-cell founda- 

 tions produce a comb that approximates very closely the lightness 

 of that which is naturally made by the bees. 



10. When heavy foundations are used, the extra weight of 

 the comb built upon them is due more to the extra weight of the 

 cell wallslthan to the heavier midrib. 



* Possibly this is only done where there are actual perforations of the comb.
