 dykes running east arid west in it' and 50 feet thick, wTiich has mar- 

 belized thfe dolomitic limetsone. This marble, weafhers Into granule^ 

 about 54 inch thick^ which form the sand. The rocks are much smoothed 

 by wear. The mountain has been quarried much in fhe past for tomb- 

 stones, is hard, and in some cases has twsted grain. Vegetation on the 

 mountain is mostly shrubby. The so-called Parkinsonia (Lysiloma) with 

 the yellow outer bark and white inner bark has the bark cracking off 

 like the birch, leaving the white inner bark smooth and with a green pulj> 

 underneath, then very compact and hard and heavy white wood. *t grow* 

 scatteringly in the crevices. It is the. same, one described from Dillers 

 mine, 20 miles out, 20 feet high, with flat . top, and with several slcB.Jer 

 strict branches', has a very graceTul and iiry. appearance waving in the 

 wind. Then there is a low and cordate-leaved shrub, 3-6 Tect high, wih 

 the same kind of bark (Jatropha). Its leaves turn yeHow with age, no 

 flowers or fruit, looks like a Euphorbiaceous plant but sap not milky, i. 

 is a graceful plant with many stems. Beneath the !"""/^''' .'' ^"I""; 

 soft pulp which goes deep, but the center of stem is shreddy and does r"t

 gladiate stipular spines inflated and occupied by ^{inging ants much 

 branched and spiny. The *- rnesquit is also. the Pal^
