Note 58 — Chapter XV

My friend Mr. Graham Anderson presented to the Durbar, at the meeting of the Representative Assembly in 1892, an interesting memorandum on rainfall in Mysore, and the influence of trees on the condition of climate, and in this he has given a return of the rainfall for a section of the Manjarabad Talook, stretching inland from the crest of the Ghauts to about the termination of the forest tract—a parallelogram of fifteen miles in length from west to east, and about four miles from north to south. This section shows, from April to end of August, a rainfall of 291.53 inches on the extreme west, as compared with 44.21 inches on the extreme east. But it is remarkable that this variation of no less than 247.32 inches occurred on the northern side of the tract, the variation on the southern side being only from 232.46 inches to 72.42 inches, or a difference of only 160.04 inches. This shows an extraordinary, and at present unaccountable, deflecting of the South-West Monsoon current. Mr. Anderson remarks that, though in heavy weather and with favourable winds, the Monsoon rain is often carried to a considerable distance to the east of the termination of the forest tract, it is of common occurrence to find an almost total cessation of continuous rain a few miles beyond the forest zone.
