trap the wild hogs, although they were numerous. They 
i said the rainy season is the time for hunting. I first 
} thought it was for the protection of the young, but I 
soon learned that in the rainy season the hogs were much 
better eating. Toward the last of my stay in the moun- 
e tains I collected a number of oaks with large and abun- 
dant acorns, and my Manobo companion always in- 
formed me that they were exceedingly good chow or food 
for the hogs, and since many of these trees were coming 
into fruiting state at this time, I could understand that by 
the rainy season from November to February the hogs were 
practically fattened on the acorns. See volume vr, article 100 of 
these Leaflets. 
The Manobos, like the Bagobos, prepare two kinds of 
traps—the latch and spring trap and the stockade kind. The 
latter kind consists of sharp pointed bamboo steaks driven slant- 
ing into the ground at the bottom of small gulches across hog runs. 
When the hog runs into them with his full force he is usually 
" wounded fatally. I was told when the traping season began each 
Manobo had a certain district, and no tresspassing was done. 
They have a great fear themselves for their traps, for the 
Sharp bamboo points or spear arrows are frequently poisoned. 
The latch and spring trap or balatic as they are called, 
drive the bamboo arrow clear through a hog or deer. 
Around Bayabas and even along the Minusuang River 
there are but very few bamboos. During my three month's 
Stay I confined my collecting in the dense and humid for- 
ested flats, along the wooded ridge up to Lake Danao and along 
the Catangan Creek. Very little was collected in the valley which 
I planned to explore later in the season after the rains had 
Started. The frightful storm and its effects paralized my activi- 
ties, and I decided to leave, knowing that in the field there were 
many plants I would like to have added to my collection still. 
The writer has always found the ridges and gullies just below 
the real summits of our high Philippine mountains the 
richest and most productive of vegetation. The plants in 
this altitudinal section all appear to need high altitudes yet 
the real summit exposures seem too severe for them.  There- 
fore, they seem to cluster around the summit in partially 
sheltered places from certain directions. Here they are densely
