The true yams constil ate an Lmportanl group of starchy tuberous-rooted food plants 

 and should not be confused with certain varieties of sweet potatoes thai are called 

 yams in our Southern States. They should be grown and used largely in those 

 warm regions of I lie world where t hey will thrive and into which people demanding 

 white potatoes have to import t hem from cooler regions, in the island of Trinidad 

 the production of the yam, cassava, taro, and other starch} rool crops has been so 

 increased during the war that the necessary demands on the wheal supply of the 

 world and on l ransnortation for carrying Hour and potatoes to that island Dave been 

 materially reduced. (Photographed by Edward Simmonds, October L'u. 1916;
