Cjiap. XV. SEARCH FOll C. OVATA. 265 



low, appeared to be of considerable size. These peccaries 

 come down in herds of thirty or forty to the clearings, during 

 the night, and do much damage amongst the roots. Some 

 are black and white, and others of a leaden colour. 



After ascending for several hundred feet we came to trees 

 of C. pubescens, which appear to belong to a zone just below, 

 but in contact with the C. ovatce. Their leaves were eaten 

 by a caterpillar, red at both ends, with a horn, red stripe 

 doM'U the back, and red spots on each side, body striped 

 green and yellow. Some hundred feet higher there were 

 large trees of both varieties of C. ovata, growing in very 

 moist parts of the forest, where the trees were covered with 

 Hymenophylla and dripping moss, the former a sure sign of 

 extreme humidity. The ground was . covered with fallen 

 leaves to a great depth, and there was a good deal of shade. 

 We collected seven plants of C. ovata, var. a vulgaris, and 

 eleven of C. ovata, var. ^ rufinervis, five of which were 

 strong healthy seedlings, the remainder being suckers, with 

 spreading roots of their own. With the C. ovatce grows the 

 Oarhua-carJma chica (CascariUa bullata, Wedd.). 



In descending from these heights I came to a tree which 

 IMartinez called copal, but the trunk rose to such an extraor- 

 dinary height, without branches, that I was unable to make 

 out the appearance of the leaves or flowers. The bark was 

 covered with a milk-white fragrant resin, of a nature analo- 

 gous to gum thus or gum elemi. The forest also abounds 

 in vegetable and bees' wax, and in many varieties of gimis 

 and resins. 



On May 11th, as we had now collected a sufficient number of 

 chinchona-plants, including those of the shrub Calisaya which 

 we intended to take up on our return across the pajonales, to 

 fill the Wardian cases at Islay, Mr, Weir began to make up 

 the plants in layers, with plenty of moss between them, ready 

 for sewing up in the Kussia matting. Having heard that a
