Near view of a coconut grove. Luisiana, Province of Laguna. On the left side 

 of the trunk on the level of the native's head almost hidden by the leaf 

 stems, is hung a bamboo joint, attached to a flower stalk, for collecting 

 the sap. The bamboo bridges from tree top to tree top facilitate the 

 collection of the sap. By climbing one tree the tops of many others 

 are thus made accessible. (Photograph by Martin.)
