THE CUBA REVIEW 



CANE TRANSPORTATION IN PORTO RICO 



The conditions showni in the accompanying ilhistrations-will. in a measxire, account for the 

 fact, in eight years, Porto Rico has ahiiost doubled its export of sugar, the figures for 1909 

 showing 244,257 long tons exported, while for 1917 the estimated figures up to Mareh 81 are 

 412,000 long tons. 



The figures given indicate not only a big increase in acreage l)ut also improved methods of 

 handling the cane. 



These scenes were photographed at Central Constancia, Toa Baja, P. R. This plantation 

 is the property of the well known Compania Azucarera del Toa, San Juan. Under the presi- 

 dency of Don Rafael Palacios Apellaniz, this company is kno^vn as one of the best managed 

 sugar concerns in Uncle Sam's island domain. 



Fig. i shows a heavy Koppel locomotive of 110 H. P. hauling a train of seventy-five sugar 

 cane cars of 114 ton capacity each. These cars are of specially heavy construction and have 

 been in service for a considerable period with highly satisfactory results. Although these cars 

 are rated at 13^ tons capacity, their construction permits a much heavier load. 



Fig. 2 shows some Koppel side dunip cars used for road construction in the \icinity of 

 Central Constancia. In this work the motive power is furnished by oxen since the intermittent 

 operation of the cars would not justifj- the expenses of a locomotive for this work alone.
