When rain falls into the evaporator it is not necessary to reduce the weight to 12 lbs when the fall of rain should be more than sufficient to fill the evaporator which will seldom if ever occur.

The reason it is not filled in the first instance is to leave room for rain and weights are supplied in excess of 12 lbs. It is necessary to be very careful with the weights and measuring. I find on examination that many of your results last month are wrong.

I have to urge your compliance with the order issued by the Superintendent of Telegraphs to send in your results daily.

I have &c
