THE CENTRIFUGAL MACHINE. 173 



two working models could be fairly managed by hand, and 

 the exhibiter showed the principles involved, and fully ex- 

 plained the process. This is the American machine, invented 

 and put in practice simultaneously with the Swedish and 

 Danish separators, which have attracted so much attention in 

 Europe the past year, but entirely independent of them. 

 Rev. H. F. Bond of Northborough has been the principal 

 inventor, and the models exhibited were his ; but he has had 

 the aid of Mr. Edward Burnett's good judgment and practi- 

 cal experience in making the necessary modifications and 

 improvements. The first completed separator put into use 

 in this country was built by D. M. Weston of Boston, after 

 the Bond-Burnett patterns, and is now in successful opera- 

 tion daily in Mr. Burnett's dairy at Deerfoot Farm, South- 

 borough, Mass. 



A number of the creamers, churns, and butter-workers in 

 the collection, were shown in operation, greatly increasing 

 the interest of the exhibit ; and this was rendered possible 

 through the generous action of the Greenfield Farmers' Club, 

 in supplying milk and cream for the purpose, and providing 

 an efficient committee to attend to the wants of the 

 exhibiters. 



Since the meeting and show, several prominent manufac- 

 turers have expressed extreme satisfaction with their experi- 

 ence in exhibiting dairy apparatus at Greenfield, stating that 

 they never met so intelligent and earnest an audience ; the 

 visitors all seemed bent on gaining information, knew just 

 what they wanted, and were quick to see the merits and the 

 faults of the many new appliances. 



Adjourned. 



THIRD DAY. 



The morning session commenced at ten o'clock, J. H. 

 Demond of Northampton in the chair. 



The Chairman. The subject announced on the pro- 

 gramme for this morning is one of the most important that 

 can be presented to those interested in the dairy, and the 

 gentleman who is to address you is one of the most thor- 

 oughly-posted men on that subject in the country. I have 

 the pleasure of introducing Col. "Willis P. Hazard of 

 West Chester, Penn.
