ed, orseemingly connected with the duties of this office, are authorized by 

 it, unless such circulars are dated from the office of the Chief Signal Officer 

 at Washington, D. C, and are authenticated by the signature of the 

 Chief Signal Officer or by that of an officer acting under his special

The Weather Services of Iowa and Missouri continued to grow not- 

 withstanding, and that of Iowa was made a State Seivice by the Seven- 

 teenth General Assembly, in 1877. 



When Gen. Hazen became Chief Signal Officer in November, 1880, 

 a more liberal, not to say more enlightened policy was soon manifest, 

 and the great value of State Weather Services was fully recognized. 

 The Signal Service now co-operates most heartily with them. Since 

 that time many states have followed the example of Iowa and Missouri, 

 namely : Alabama, Arkansas, Illinois, Indiana, Kansas, Louisiana, 

 Michigan, Minnesota, Mississippi, Nebraska, Nevada, New England, New 

 York, New Jersey, North Carolina, Ohio, Oregon, Pennsylvania, South 

 Carolina, Tennessee and Texas. Several of these states have made 

 adequate appropriations for carrying on this work ; among these, Iowa 

 and Ohio have done most. 



The present Chief Signal Officer, Gen, Greeley, has done much to 

 encourage the establishing of these State Services, although he states in 

 a personal letter that he does not feel that the National Service has any 

 function to perform in connection with them save to give such slight aid 

 as may be possible, and to give the benefit of its advice when so de- 

 sired. 



He adds that in his opinion the cost of making known the climate 

 of a state should fall upon the people of that state, and when, as in the 

 case of Missouri, it has a climate suited to the production of all the 

 great staples of the country, there is no reason why the state should 

 hesitate to make this known. 



VALUE OF STATE WEATHER SERVICES. 



To show how valuable the information collected by a State Service 

 may be, the following is cited : 



In Iowa, horticulturists have found much trouble to grow apple 

 trees by reason of the severe winters. A prominent horticulturist im- 

 ported varieties of Russian apples, introducing them with the statement 

 that the climate from which they came was similiar to that of Iowa. 

 They were widely planted, and there was a very general neglect of 

 native varieties which had in part succeeded. Dr. Hinrichs made an ex-
