32 State University Experimental station. 



about 40 acres, but the infection stopped them, and in about a week there was none 

 left to speak of; and, althongh it was dry and corn was considered a failure, I raised 

 400 bushels, but without the infection I do not think I would have had even good 



fodder.

E. A. Markey, Warrensburg, Mo. — My first trial was with some infected bags sent 

 from the station by you, and was a failure. The second attempt was from infected 

 bugs received from your assistant. In putting them on the field of corn, I only had 

 time to scatter on one row of corn. I went over tke field seven days afterwards, and 

 found the infection on 15 rows of corn. I then gathered more bugs, in all about 

 one quart, and infected them, and scattered them on the same piece of ground. 

 During this period a shower of rain fell, and the sun came out warm. The results 

 were very surprising, as the infection had not only spread over that field, but to a 

 field one-fourth of a mile north; also to the wheat field lying between the two. The 

 weather then turned hot, and, as the ground got very dry, I could not succeed in in- 

 fecting bugs any further in the fields. I believe that where one can have the time 

 to spend on this, and in the right kind of weather, success will crown his efforts. 



E. Marquis, Mulberry, Kas. — Successful. The weather was very hot and dry for 

 about eight days after I began scattering out the diseased bugs. I could see no ef- 

 fect from them at all, and was getting discouraged; thought it was no good; then 

 rain came, and, to my astonishment, the disease seemed to take them like magic. 

 They were dying by the thousand, with the white fungus on their backs. The result 

 proved to be an outright success. 



A. E. Martin, Assaria, Kas. — Doubtful. As to the result of my experiment with 

 chinch-bug infection, I cannot say whether it was successful or not, but will tell all 

 I can about it. When I first sent to you for infected bugs, last July, the chinch 

 bugs here were coming out of the wheat fields in countless numbers, and first at- 

 tacked a field of sorghum, where they killed about an acre in a very few days, but 

 later they did not seem to work as fast. I took the bugs you sent me and put them 

 in a box according to directions. When the time was up I took the bugs and scat- 

 tered them through the fields. There were quite a number of white-f ungus-covered 

 bugs on the bottom when I did so. Some days later I went to examine the fields, 

 and, upon overturning lumps of earth, I found what appeared to be large bunches 

 of dead and dying bugs, but not any white-fungus-covered ones; yet I thought that 

 it was due to the infection. Later in the day I went over to two of my neighbors 

 and found that the bugs were bunched and almost disappeared out of their fields, 

 also, although they had used no infection. Later on I sent you some of those ap- 

 parently dead bugs, but which upon your examination proved to be only dried 

 skins, as you told me in your reply. I kept the infection box going for two or 

 three weeks, but after the first time I was able to find very few fungus-covered bugs 

 on the bottom. The weather at the time was extremely dry and hot, which I sup- 

 pose was not favorable, but the chinch bugs did very little damage after I started 

 to use the infection; but as this was equally true of fields where no infection was 

 used, I cannot say what caused them to cease doing injury. 



S. E. Miller, Roxburg, Kas. — Successful. I think it was a success. Think I saved 

 a field of sorghum and a part of a cornfield. Had a field of rye, and, as it was ready 

 to harvest, I scattered bugs thick along No. 1 line. Had hot bugs enough to go 

 through between the corn and rye, so gathered more bugs, and When they were ready 

 to scatter, went to No. 1 line and found bugs in the sorghum from 10 to 40 feet. 

 Thought at first the crop was gone, but on closer examination I saw that there was 

 something the matter with the bugs; they were not on the stalks, but were running
