subsequently revived. Sent yon a number of chrysalids and larvae brought in on the 

 3d instant. 



November 5. — Temperature 48*^ F., 7 a. m. Transferred 44 moths from box No. 5 to 

 box No. 7. Eggs now being deposited all over box (glass) No. 7. 



Made box No. 9 without bottom. Loosened the earth so as to bring it into the con- 

 dition of an ordinary fresh land cotton bed; sunk the box 2 inches. This will give 

 normal earth temperature ; nailed a board over a part of the top to protect from rain 

 in order to afford hibernating shelter for the moth ; over the rest of the top tacked a 

 piece of coarse cloth for protection and to secure moths, through which rain will 

 percolate, and where I shall place sweets. All under rough cover constructed for the 

 purpose. Placed in this box 90 chrysalids brought in on the 3d. This is done in imi- 

 tation of nature. 



Put under same shelter box No. 10. This is a shallow box filled to within 2 inches 

 of the top with loose soil, top arranged as last. This has a wooden bottom, but wood 

 being a bad conductor would modify temperature. Put into this 140 chrysalids, 

 which will be treated as last box. These boxes afford an excellent test for hiberna- 

 tion of the moth. In cutting up tomatoes six Boll Worms (Heliothis) were met with, 

 which were sent to you. Being found in the fruit, flagrante delicto, settles the ques- 

 tion of its feeding upon other plants or fruit than cotton. Visited a cotton-iield and 

 found the green cotton uninjured, though on the day before the temperature was 32° 

 F., but not of sufficient duration to produce ice and destroy vegetation. Brought in 

 eggs, larvae, and chrysalids. N© signs of Heliothis. 



November 6. — Temperature 56° F. Rain. 



November 7. — Cloudy and misty; temperature 56° F., 9 a. m. One dead moth in 

 No. 7. Temperature, at 1 p. m. in the sun, varied from 74° to 84° F. ; clear and cloudy 

 alternately. 



November 8. — Sent you a box containing Heliothis chrysalids and larvae (Aletia). 

 Rain p. m. 



November 9. — Put in flower-pot 3 larvae (Heliothis) in tomato, and one in cotton boll. 

 Introduced 60 Aletia chrysalids into box No. 4, gathered on 3d instant. Put in box 

 No. 11, 60 chrj salids, gathered on same date, wooden box, glass top, to be kept in 

 house. Put in gauze bag, wooden bottom, 76 chrysalids, gathered 27th ultimo. 

 Temperature 56° F., 1 p. m. ; rainy and raw. 



November 10. — Cloudy and foggy; temperature 62° F. 



November \l. — Cloudy and foggy ; temperature 66° F. Rainy day. Visited a field 

 in which I found fresh chrysalids and larvae. Foliage abundant. East side of field 

 protected. 



November 12. — Introduced 18 fresh chrysalids into box No. 1. Temperature 56° F., 

 7 a. m. 



November 14. — Temperature 40° F., 6 a. m. ; clear; wind north. Eleven moths in 

 No. 4 ; 12 dead moths in No. 5 ; 3 moths in No. 1 ; 13 in No. 11 ; 13 dead moths in No. 7. 

 Visited a field of late cotton, where I found foliage fresh and partially nibbled by 

 the worm. Found a few young bolls perforated, the first evidence of Heliothis in my 

 search this fall in cotton; the field a small one, contiguous to a garden. Found a few 

 Aletia chrysalids; no eggs or larvae. Aphides clustered in colonies within the in- 

 volucre chiefly, and dark in color. 



November 15. — Temperature 42° F., 6 a. m. Clear. Wind north. Visited a field 

 where the foliage begins to show the effects of frost. Found a few chrysalids freshly 

 folded ; no larvae or eggs. Found also a few young bolls eaten into, but whether by 

 Heliothis or other insect am unable to say. The forms were not flared as usual. No 

 other signs of Heliothis. Aphis and many other insects, especially Lady Birds, found 

 well secreted. 



November 16. — Temperature 46° F., 8 a. m. Visited a fresh field. Found it partially 

 eaten by the Cotton Worm ; leaves green and fresh. No larvae or eggs to be found. 

 Fresh chrysalids abundant and moths issuing therefrom. This is probably the sixth 

 brood, and is certainly the last to appear in cotton. Brought in a number of chrys- 

 alids. 



November 17. — Temperature 58° F., 8 a. m. Wind south. Introduced 25 fresh chrys- 

 alids in box No. 5. Removed 6 dead moths from same. Transferred 16 moths from 

 No. 5 to No. 7. Introduced 25 fresh chrysalids into box No. 4. Placed these two 

 boxes under shelter, with boxes Nos. 9 and 10 on the ground. Placed bottles with 

 eggs under same shelter, on the earth, inverted. Visited cotton-field and found 1 fresh 



egg- 



November 18. — Temperature 76° F., la. m. Removed 5 dead moths from box No. 7 ; 

 5 from No. 11 ; 20 moths in No. 11 ; 12 moths in No. 1 ; 4 dead moths in No. 1. Vis- 

 ited a field of late fresh land cotton. Found fresh eggs of Aletia, as many as 7 

 on a leaf. In my glass box No. 7 the eggs are deposited indiscriminately upon glass, 

 cotton leaves, stalks, and forms. 



November 19. — Temperatute 46° F., 12 m. Wind northwest. Rain. 



November 20. — Temperature 30° F., 6 a. m.
