2. 'The e tapping experiment was first undertaken in July, under 
the impression that the flow of milk would be more abundant 
Small bamboo pots were, in the first instance, affixed to the 
trees by means of well-wrought potter's clay, and above them 
small pieces of tin were also placed in such a position as to 
protect them from the rain ; but, as the clay yielded to the rain 
and fell to the ground, tapping had to be undertaken at intervals 
between the showers, the bamboo pots being affixed by sharpening 
th i 
followed by the «hitsi " collectors. In order to obtain the 
largest UT of oa in los shortest time possible, numerous 
incisions were made on the trees. The incisions were made in an 
upward diebdon fs EO VEHÉIRE as required. 
The quantity of milk collected was so small in the intervals 
between the showers that it was deemed necessary to limit the 
experiment finally to five of the larger trees on the west bank of 
the Bókchaungale, which flows through the plantation. "The milk 
was found to flow much more freely from these trees, although 
not much AN than the trees first experimented upon. The 
was thickest, while at a height of 6 or 7 feet it was almost nil. 
wing to continued wet weather, it was found necessary to dry 
the milk over a fire and keep it subsequently in a warm place 
near the fire for about three weeks. 
3. The experiment was renewed between 22nd and 26th 
November, when the rains had fully ceased, 42 trees being 
operated on, viz. 5 to the west and 37 to the east of the 
Bókchaungale. 
The method of tapping was the same as that followed previously : 
but the yield from each Peta ns being small (less in fact than 
as the case in the rains), Ph ral trees were tapped to nnd 
utmost extent, and, by co mantiy collecting the milk before 
had time to dry, the QUatttity now forwarded was obtained, vá. 
3 oz. from the 5 trees to the west, and 9 oz. from the 37 trees to 
the A. of the Wet yg
