and not always that, to pay the current expenses of correspondence and dis- 

 tribution of literature, and to maintain a relatively small line of educational 

 work. 



With permanent endowments in our Audubon societies, which, once estab- 

 lished, ought to be gradually added to instead of decreased, the progress of 

 nature-study and bird-protection could not fail to be greatly accelerated, 

 wliile the results which might be obtained by a body of trained field-workers 

 throughout the country can hardly be estimated. 



Is this plan too large to meet the present opportunities? Who shall say?

FOR TEACHERS AND PUPILS 



As has been suggested heretofore, in schools where no definite time is set 

 aside for nature-study, the most successful method of teaching this subject 

 seems to be by correlation with other studies. 



In view of the fact that so many teachers have to meet this condition, 

 a series of exercises in which nature-study will be correlated with other branches 

 is to be presented in this department. It is hoped that these exercises will be 

 practical as well as suggestive. Teachers are invited to send in criticisms and 

 also, methods of teaching nature-study which they have personally tested.

 such as music; still other things which we can smell but can neither see nor 

 hear, such as the fragrance of flowers; and many things which we feel but do 

 not see, hear or smell, as, for example, the softness of a cushion or the prick- 

 liness of a thorn. 



The weather is something which we feel more than we see or hear or smell, 

 although at times we may see parts of it, hear parts of it, and even smell some 

 of it. 



The weather is really not a thing at all, but only a state, or condition, of 

 something. This something is the air we breathe, and the air far up above 

 us which we could not breathe and live, and the air around not only us but 

 also the entire earth. 



All of these kinds of air together are called the atmosphere, and you must 

 learn to think of the air or atmosphere as something which is movable, which 

 can be made hot or cold, wet or dry, which has weight and height, and which
