In this paper reasons bave been given for the modifications of the major climatic provinces and the physical basis for the subdivisions is also discussed. Some brief survey of the subregions is also attempted.
The factors that influence the rate of growth, length of life, fecundity, abundance, death rate, or time of appearance of vegetation are obviously climatic. And the rainfall and temperature conditions are the most important factors in defining the large areas of crop distribution and plant varieties.

The work efficiency of the personnel of the whole University is thus more of less reduced. But from the hygienic point -of view the new Campus is muchbetter situated than theoldone, why is ma aria more serious there than here?
Po nts actually determined by the terrestial survey are only points occupied by the instrument and rod; details away from these points are sketches of which the accuracy depends upon the closeness of such points and the experience and ingeniousness of the surveyor. Thus the inexpressive and inexact contour lines as often found on certain topographical maps can although be improved to some extent but can not be altogether eliminated.
