226 THE SUGAR BEET. 



wooden pulleys; their arms are horizontal. These sup- 

 ports are placed at distances varying from 60 m. (196.8 

 feet) to 80 m. (262 feet). The buckets conveying the 

 beets have a half cylindrical shape, and a capacity of 

 about 50 kilog. (110 lbs.). Their movement is due to 

 the adherence to the wire rope. The placing of these 

 buckets on the latter is accom]3lished by hand, and 

 when in contact with the pulleys on the support they 

 pass over them in consequence of their momentum. 

 When at their destination they leave the end drum, pass- 

 ing on a small track, which is at a tangent to the same. 

 The acquired velocity is sufficient for the movement 

 to continue for a short distance. About 7500 kilosr. 

 (16,500 lbs.) can thus be carried per hour, and in ten 

 hours 165,000 lbs. The pulp is returned fi'om the 

 factory to the farms in a given direction in the same 

 manner. All calculations made |0.06 will represent 

 the cost for hauling per kilometric ton. This sum does 

 not include the placing in silos or gathering of the 

 roots. 



2. Promn's Idea. — Here the rope is fixed at both 

 ends. The baskets move by gravity on a slant of 21 

 mm. per metre. This idea in many respects is most ex- 

 cellent. The lope is supported in the air by an inge- 

 nious apparatus, as shown in fig. 45. Evidentl^^ if 

 some precautions were not taken it would be likely to 

 break in consequence of repeated shocks received at 

 the point of intersection of the rope and support at 

 the passage of each basket. To avoid this, to the arm
