into the soil. The cage can be used out of doors as well as in the 

 insectary, and without materially affecting the plant or disturbing the 

 insects feeding upon it. When used with the wooden bottom the metallic 

 base raises this above the damp soil, thus preventing the decay of the 

 lower portion of the cage. 



But " one supply reveals another want," and we soon found that 

 there was a need of some method of keeping our notes and records con- 

 veniently attached to the proper cage to which they belonged, as well as 



to protect them from being wetted when- 

 ever the benches were wet down with the 

 'hose. This led to the use of a holder of 

 galvanized iron with a sliding glass front, 

 Fig. 26. fastened to the cages as shown at the left 



in Figure 25, and also in actual use on the cages in Plate 4. The holder 

 is two by three inches, the sides turned over, and one end over these, while 

 the other end is left a little longer and rounded, with a small hole to pass 

 over a small nail or brad, while the other end is held by a small screw- 

 eye, such as are used on picture frames to which to attach the ends of the 

 cord or wire. The note sheet is folded the proper size and placed in the 

 holder, and the rather close-fitting glass slide pushed in over it. The 

 sheet is so folded that all of the notes will come on the same side, and 

 each space or page is consecutively numbered, and, being all of a uniform 

 size, these sheets when filled or the record finished, can be filed away for 

 permament preservation. This holder cannot easily become detached 

 from the cage to which it is fastened, the notes are preserved from being 

 injured by wet, the galvanized iron does not rust them, and the last 

 record can always be seen through the glass cover without removing it 

 from the cage. With slight modifications, this holder can also be used 

 out of doors on shrubs and trees. For this purpose, what shows as the 

 lower end in Fig. 25 is cut square oft" and a similar triangular piece 

 is soldered to the back of the upper end to accommodate a fine wire 

 which is used not only to attach the holder to the object, but the end 

 running downward along the back is hooked over the lower end of the 

 holder, thus effectually preventing the glass slide from being shaken out 

 by the action of the wind. On cages outside, it is of course used in the 

 same way as in the insectary.
