Both mills are heavily double geared with steel pinions and crown 

 wheels throughout, neither being provided with hydraulic or other 

 safety or pressure regulating attachments. The back mill is driven by 

 its lower roll shaft, and is provided with a roughening device believed 

 to possess much merit. The mills are separated 15 feet between cen- 

 ters. Saturation between them was first introduced this season, be- 

 ginning about the middle of its third run. This will find full discussion 

 later. 



This apparatus is operated upon a plan quite unlike that customary 

 in the milling of cane in Louisiana in that the feed upon the carriers is 

 maintained as uniform at all times as possible, variations in the amount 

 of cane consumed being regulated to that received from the fields as 

 nearly as practicable by altering the speed of the engine, the governor 

 to which is provided with a speeding device. The speed of the centrif- 

 ugals is likewise regulated to the necessaries of the sugar being dried. 

 The otherwise constant necessity for a change of the mills "set" is thus 

 obviated, insuring a uniformity of expression and a reduction of time 

 lost to be better secured only, it is believed, by the hydraulic-pressure 

 regulator. The average juice extraction of this mill for a series of years, 

 expressed in percents of the canes' weight, has been : 



That of the three-roll mill prior to the erection of the supplemental 

 rolls, the same engineer remaining in charge throughout, was 



* Inundated ; no crop. 



This indicates an average advantage, by campaigns of 7.58 per cent, 

 juice on the canes' weight, to the credit of the supplemental mill, in 

 which no account is taken of the variations in the character of the 

 canes or the quantity of these treated per hour, which remain much 

 more constant in Louisiana than upon more tropical estates. 



MINOR CONVENIENCES. 



The minor conveniences of the establishment are as perfect as they 

 are unusual, and are mentioned as contributing largely to the excel- 

 lence of results attained by it, and as worthy of imitation. Twenty-four 

 sirup and molasses tanks and blowups, uniformly of 3,500 gallons ca- 

 pacity each, and 300 sugar- wagons, together with the entire plan and 

 plant of the house, offer exceptionally favorable opportunities both to
