elaborate notes for the benefit of those persons who wish 

 to make a serious study of the objects or to gain exper- 

 ience and efficiency in somewhat advanced fields of 

 research. These boxes each contain one botanical and 

 one zoological specimen. Most of the notes have been 

 made by Dr. Ward, Dr. Shanks and C. M. Vorce. Others 

 are invited to contribute for next year. Some of the 

 members have testified their high appreciation of the 

 boxes and the notes as being superior to any of past years. 

 The membership is divided into circuits. While a box 

 is passing through a circuit, including six or eight 

 addresses, it is out of sight of the Secretary. If the box 

 fails to complete its circuit on time, the Secretary is put 

 to great trouble in tracing it. This is where "one sinner 

 destroyeth much good." Last year a circuit was neces- 

 sarily dropped because no boxes could be got through it 

 or could even by any amount of special effort be got back 

 from it except after months of delay which wassimply ruin 

 ous to the plans of the officers. It would give us pleasure 

 to publish the names of the members of that, circuit if the 

 officers would kindly furuish them to us. If, however, 

 they neglect the system of fines, suggested above, they 

 will loose a part of our sympathy. There are some vacan 

 cies in the well behaved circuits and co-operation is 

 desired in finding suitable persons to be made new 

 members.
