KANSAS ACADEMY OF SCIENCE. 89 



Weather Service will be so far perfected that no question will exist as to its 

 permanence. It is not, of course, expected that the fruits of its work will be 

 gathered or apparent the first or the second year. It may be changed in 

 many details when experience shows such changes profitable, and ultimately 

 should be considered a permanent feature of the Agricultural Department 

 of the State, and be under State management. The object of bringing it at 

 this time before the Academy, is to present its claim to scientific interest, and 

 to secure sympathy and cooperation in a work which, if done at all, must be 

 the labor of many hands.
