worms. More than seventeen varieties of the nut arc 

 known in India alone, wliere the trade in the nuts 

 (seeds) exceeds S30,(X)0,000 yearly. It is also used 

 extensively for medicinal purposes. 



The cultivation of areciis is not difficult. They must 

 be grown in a tropical house with a day temperature 



of 75° to 85° and a 

 night temperature 

 of not less than 60°. 

 Young plants thrive 

 in a mixture of 

 equal parts of peat 

 or leaf-mold and 

 loam, while older 

 plants wiU do best 

 in a mixture of 

 loam and sand, 

 equal parts, mixed 

 with a liberal 

 amount of well-rot- 

 ted cow- or horse- 

 man u re. Water 

 freely, at least every 

 other day. As young 

 plants, they form 

 beautiful decorations and when old are perhaps the 

 most graceful and delicately fohaged palms in culti- 

 vation. G.C. II. 22:427.
