culture, were still imperfect, and though sold at an extrav- 

 agantly high price— through no fault of Mr. Eoot^, as he 

 informs me — were in great demand. Next, Mrs. F. Dun-

(Fig. 103) that the foundation would have a very thin 

 base and high thick walls which, in the manufacture, 

 were not greatly pressed. These three points are very 

 desirable in all foundation — thin base and thick, high 

 walls, which shall not be compactly pressed. 



Mi'S. Dunham is not only entitled to gratitude for the supc- 

 rior excellence of the macliines slie manufactured, but by put- 

 ting so excellent a machine onto the market at a lower price, 

 all roller machines had to be sold more reasonal>ly. Mr. Van- 

 dervort also improved the rollers, so that his machine secures 

 •ihe same results as does Mrs. Dunham's, while the form of the 

 foundation is somewhat more natural, tlK)ugh not preferred l)y 

 the bees I think. Another form of foundation — that with flat 

 bottom — is made by the VanDeuseu mill. This has a very 

 Ihin base, and is very handsome. It Avas made to use with 

 ■oires. In my experience this flat bottom foundation is not as 

 acceptable to the bees as the other kinds. ]\Ir. Root has kept 

 his machine abreast with the latest improvements. Mr. Pel- 

 ham hag invented rolls that are nrade in rin";s or sections.
