of the hoisting rope or cable is hitched to the sling, and the entire load 

 is hoisted out of the vehicle. A very convenient form of sling for trans- 

 ferring cane by gasoline loader from sleds to cane cars in the Island 

 of Hawaii is made in two parts with separable hinge device in the center 

 which can be opened by pulling a rope and discharging the entire con- 

 tents of the sling into the car when it is in proper position. 



The storage of daily supply. — The small mills using cart transporta- 

 tion generally discharge all of the cane from the carts onto the ground 

 from whence it is taken by hand and fed into the mill. Occasionally a 

 cane carrier is used and a part of the carts are discharged directly onto 

 \he carrier, which feeds it into the mill. When carts are not discharg- 

 ing cane onto the carrier the load is kept constant by transferring the 

 cane by hand to the carrier from where it has been placed on the ground. 

 The more modern mills using railway transportation have very long 

 cane carriers onto which the cane is discharged from the cars at such 

 rate as to keep all parts of the carrier constantly loaded. When carts, 

 wagons, or cars are discharging onto the ground the cane may be placed 

 on the carrier direct by hand or a power grab, but when large quantities 

 have to be discharged into the yards it is usually necessary to load the 

 cane onto cars by means of a heavy derrick and run these down the 

 tracks to the carrier where it is discharged in the same manner as 

 when received directly from the field. The larger mills having ample 

 capital to provide the equipment necessary for the economic operation 

 of the factory generally have an ample supply of cars for storing a 

 supply of cane sufficient for the operation of the mill from ten to twentv'- 

 four hours. The amount of cane harvested and transported to the mill 

 during day-light is generally sufficient to keep the mill supplied for at 

 least twenty-four hours. When an abundance of cars are available a 

 surplus over this is also maintained in order to avoid the stopping of 

 the mill should an accident occur on the transportation line. 



Weighing. — A definite knowledge of tonnage }-ield and accuracy in 

 the results of milling can be had only when the weight of cane harvested 

 and delivered to the mill is known. It is necessary to weigh all cane 

 received at the mill and to carefully check every process during its 

 manufacture. The most common form of scales to be used for weighing 

 cane are the wagon scale for carts or wagons and railway track scale 

 for cars. The loaded cars are run over the scales, weighed, and after 

 being unloaded the empty cars are weighed and the difference taken 

 as the amount of cane delivered on the carrier. This is the point at 

 which the official weights for the purchase of cane, the payment of 

 contracts based on tonnage or the division of the crop are generally 

 taken. The scales should be under a shed, kept in good repair, and 

 tested reffularlv for accuracv.
