PLATE V 



Fig. 11. Timberliue at Fontein (Ac2), northeastern side of Aruba. 

 In the foreground and at the right are the very barren regions of the 

 exposed, northeastern shores (compare CIO, C20, and A7). The wind- 

 distorted thornbushes depend on the small streams; a few tops of coco- 

 palms locate the hofje of Fontein. In the left background is a small 

 sand dune. 



Fig. 12. Xear Perkietenboseh (A5a), southwestern side of Aruba. 

 This shows the zone of natural vegetation near the summit of the low 

 shore cliffs, on the recent limestone. Much of the ground vegetation con- 

 sists of Jatropha urens and Opuntia. The divi-divi trees are character- 

 istically distorted by the wind. Coral-reef islands are visible in the 

 background. 



Fig. lo. Northern escarpment of Seroe Spelonk (Clld), northeastern 

 side of Curasao. The foreground illustrates the rather luxuriant vegeta- 

 tion near Landhuis Hato; a small, leafless Bursera is conspicuous at the 

 left. In the background are the overhanging, older limestone cliffs of 

 the flat-topped Hato ridge (Cll, a-d). Although the physiographic 

 location of this picture is very similar to that in figure 11, the north- 

 facing escarpment is farther from the barren shore and offers consider- 

 ably more protection to the vegetation (see location on maps).
