XVIII was kept weeded and the other half left unweeded, the observa¬ 
tions on the seedling growth being continued. The weeding was done 
twice annually, once at the beginning and once at the end of the rains. 
The additional observations regarding the further development of the 
seedlings in the weeded and unweeded halves of the beds in Plots XVIII 
and XIX are given below :

32. The chief points of interest in this experiment are : 
(1) In a comparatively unfavourable season, with the normal heavy 
rainfall of 75 inches for the period June to September follow¬ 
ed by an unusually dry hot weather, the results, as regards 
the number of surviving plants at the end of the year, are 
approximately 7 times better in the cleared areas, plots 
XVII-XX, than in the shade plots XI and XII. 
(2) No damage by frost was noticed in any of the cleared areas, 
plots XVII-XX. 
(3) Taking all the weeded and unweeded areas together of Plots 
XVIII (100' strip) and XIX (60' square), the average annual 
height-growth, calculated for the 3J years period, is 8*7 
[ 192 ]
