Figure 12 is a device suggested by Calvert for rearing dragon-flies, suitable 

 environment having been obtained. The cylinders of wire netting are placed in 

 the water, and the insects placed therein. When they transform it is possible to 

 identify the adults, and consequently distinguish between young. The picture 

 given is from an experiment performed at the laboratory. 



Figure 13 illustrates to 

 photographers the possi- 

 bilities of taking bird nests 

 in-doors. The nest is that 

 of Wright's flycatcher, 

 E mp ido n a x iv r ig h t i /, 

 Baird. A position was 

 taken in front of the win- 

 dow, though out of the 

 direct sun. A black felt 

 cloth was used as a back- 

 ground, the nest being set 

 on the cloth in the angle 

 made by the table and a 

 pile of books. A mirror 

 was adjusted so as to 

 throw light into the nest, 

 as the side next the win- 

 dow was naturally darker 

 than the other. The nest 

 was several inches long, but was incUned so as to be parallel to the lens, hence 

 the observer is looking into the nest. The plate is a Seed orthochromatic, with 

 ray filter, small stop. The fluffy appearance of the surface is due to the cottony 

 material with which the nest is lined. By this same arrangement a series of 

 pictures of nests was taken, without moving the apparatus. 



The biological station will be open for the summer of 1901 from July '22 to 

 August 17. The six weeks preceding will be spent in the adjacent region col- 

 lecting. Five days of the week during the time the station is open will be spent in 

 work, the sixth will be taken for excursions. As is usual, there are no fees in 

 connection with this work, all of the material being provided free, and the teach- 

 ing force giving their time gratuitously. Those attending will be asked to pay 

 for what is broken or consumed, and to pay their living expenses. 



Accommodations are better than heretofore. The post-office, Big Fork, has 

 during the past year been established at the store close by the station. The 

 Kalispell electric light plant is across the river, and several houses have sprung 

 up during the summer. Daily mail, electric light, a railroad just built a short 

 distance away, a new hotel, and other conveniences, make living less wild and 

 more natural, and will give greater opportunity to those who wish to attend. 



As the result of the two years' work thus far accomplished, several bulletins 

 are ready for publication, and several others are under way. There is a fine 

 opportunity for work, and plenty of material, in a new country, with practically no 

 opposition ; but the workers are too few and life too short.
