In the next table are given the results obtained from rain 
gauges of two different kinds, placed in close proximity in 
the same plane, and 3ft. from the ground, the one has a lOin. 
round receiver, and the other a 5in. square one. The differ- 
ence between the amount that fell in each kind of gauge is 
very small. It is not always the same amount of difference, 
nor of the same kind, for tha excess or insufficiency is some- 
times in the one and sometimes in the other gauge, the 
average difference for the whole year amounts only to rofo 
of an inch. Thus, as I’ have said before, these gauges are 
good checks upon each other.
