accurate observations, which in the course of years must be valuable to 

 any locality in the study and adaptation of cereals. 



5. It will bring the science and methods of the Signal Service within 

 the reach of the high schools of the State, offering teachers and pupils 

 alike excellent, opportunity to study a wide range of the application of 

 science to foster and protect agricultural industry. 



(I. It will lead to the collection of rainfall statistics to enable engineers 

 to Letter estimate the supply of canals; also, the sudden downpours to 

 guard against in laying out sewers in cities. It will lead to a correct 

 knowledge of rainfall over different watersheds of the State, for the purpose 

 of giving data for supplying the waterworks of cities, towns, and villages. 



7. It will lead to the forming of reliable meteorological records for use 

 in legal cases. 



8. It will lead to a better practice of medicine, when physicians through- 

 out the State can study diseases with reliable and accurate meteorological 

 facts by their side ; and for sanitary purposes correct meteorological statis- 

 tics are invaluable to the practitioner in applying preventive remedies for 

 the public good.

To take observations requires but little time daily, and the exercise is 

 especially agreeable to those that are interested in natural science. Twenty 

 or more States have already entered on the work, with most gratifying 

 results. The complete success which is anticipated will only come when 

 each State does its part, and it should not be said that California has neg- 

 lected a matter of such importance to the entire community, especially to 

 the farmers. 



All trades and professions are more or less affected by changes in the 

 weather, and the study of the phenomena is becoming more and more 

 interesting to every man and woman in the country. 



Very respectfully, your obedient servant,

Observer Signal Corps U. S. A., and Meteorologist to the State Board 

 of Agriculture.
