attention of the public by this Station (see Bulletin 121). As the 

 paddles revolve the liquid is carried both around and upward in the 

 barrel, giving thorough agitation. With fixed tanks this device may 

 be fitted with chain and sprocket so as to be driven by the wagon 

 wheel. This has been done by Maxwell Bros., of Geneva, who have 

 a power outfit with unright cylindrical tank, the agitator of which 

 consists of two banks of whirling tilted paddles, one at the bottom 

 of the tank and one at about the middle. The mechanism is geared 

 to one hind wheel. 



The agitator in the steam power outfit made by the Rochester 

 Machine Tool Works consists of a bronze shaft, connected with the 

 engine by a flexible coupling. On the shaft are two small blades 

 similar to propeller-wheel blades, which revolve near the bottom of 

 the cask. The speed can be varied at the pleasure of the operator. 

 Agitators built after the screw-propeller model which are used with 

 some large tanks are geared to a wagon wheel by sprocket and chain 

 attachment. 



In the outfit of A. Wood & Son of Carlton Station the agitator 

 is built like the fan of a fanning mill on a horizontal shaft. It is 

 driven by means of chain and sprockets attached to one of the wagon 

 wheels. This device is frequently found in use with large tanks. 

 It gives good satisfaction. 



Morrill and Morley make a horizontal, half-round, self-agitating 

 tank. It is divided into three compartments by bulkheads extend- 

 ing to within 6 inches of the bottom, with a view to forcing the 

 mixture along the bottom, and upwards against the bulkheads and 

 ends of the tank. 



The whirling paddle type of agitator thus far has generally proved 

 the most efficient in use. These agitators continually throw the liquid 

 upward and outward from the whole bottom of the tank, giving a 

 thorough agitation. Most agitators of this type are independent
