Glass chimneys or globes were used for enclosing the plant 

 after a green bug had been isolated upon it, and as a further 

 measure of- protection against accidents or enemies, the top of 

 the chimney was covered with a piece of muslin cloth held 

 tightly in place by a rubber band. Although care was taken 

 to set each chimney firmly in the earth, yet rats and mice occa- 

 sionally succeeded in digging under the base and thus gained ac- 

 cess to and destroyed the seedling, usually causing the loss of 

 the isolated bug. Owing to the danger of these rodents, de- 

 spite the warfare that was made upon them, but little safety 

 would have been afforded by the use of muslin bags supported 

 on wire loops. Of all protective methods considered, glass 

 globes have the advantage of offering practically no obstruc- 

 tion to light and view. Any kind of enclosure, however, will 

 interfere with circulation of air and tend to increase tempera- 

 ture and humidity, and so far as muslin is used will further- 

 more reduce sunlight. All of the imposed influences produced 

 by such causes must be taken into account as being at a vari- 

 ance with natural conditions. 



Grain seedlings were grown in beds under field cages and 

 transplanted in pots a day or two in advance of actual needs. 

 By careful nursing during the hot weather a vigorous growth 

 could be secured and depended upon for sustenance of the bugs 

 in isolation. Oats sprouted in midsummer much better than 

 wheat, and always survived more successfully after being set 

 in pots. 



The process of isolating the young bugs involved the great- 

 est risk in dealing with them. They were transferred with 

 best success by means of a dampened point of a fine camel's 

 hair brush. Examples often had difficulty in attaching to the 

 plant on which they were placed. Attempts to induce them to 

 hang on a blade sometimes proved very vexatious. After some 

 losses had occurred with individuals which failed in this man- 

 ner, the placing of paper sheets on the earth surrounding the 

 stem of the plant was found to be a wise plan. Then in case a 

 young bug fell from a leaf it could readily be recovered and 

 possibly replaced by patient attempts. 



For shelter a special tent of strong canvas was erected on a 

 framework of 2 by 4 in. lumber. The posts were set securely 

 into the ground, being cross-braced to withstand heavy winds 

 or severe storms. In accordance with the changes of weather,
