 ■way into llic bnir. It seems to prefer living on tlic Inirr ratlier 

 than llie nnt. This view sliows wliat I liave called the "little" 

 burr worm. Here it is. It lives iiormallj^ in the burr. Occa- 

 sionally it eats into the nut, but it does not like the nut, l)ut 

 leaves an ui»ly liole and tlie nut afterwards frequently moulds. 



This shows tlie adult motli, tlie UoJcoccra ^ohGrii. It is very 

 similar to tlie flolcorrni f/]<iii(1ii]tifa. l)ut, accordinj^ to Kear- 

 foot, of ]\rontclair, New Jersey, it should be called a distinct 

 species, and it lias been named in honor of Mr. Sober. This is 

 one of the worst enemies. There are two shoAvn in this view, a 

 "little" and a "large" one. This is the larger one. (Indicat- 

 ing). I have tried a number of times to get the adult of that, but 

 I have failed thus far. It is easy to get them in the larval stage, 

 — you get lots of larvae, — and they will make the cocoons. 

 Normally the cocoon is made in the burr and fortunately when 

 the burr is removed the cocoon is removed; but I have not l)een 

 able to get them to mature. I do not know the adult of this 

 one. 



This view shows the hole it makes into the nut. It is cut 

 away to show it. It has not gone in very far and this has re- 

 moved all the injury done. The other one is the injured one, 

 showing the spot, in the edge of the screen. This one is injured 

 here. (Indicating). If the nuts are eaten immediately or used, 

 they arc scarcely injured; but if they are allowed to stand for a 

 time spores of various moulds get into them and the nuts soon rot 

 entirely. In this case this nut shown has cracked Ojpen, and 

 is full of black spores. I am not able to identify all the moulds; 

 some of them resemble very mncli the ordinary bread mould. 



Insect tra])S were made l)y ^fr. Sober in 1910 and placed 

 throughout the grove, and thousands of moths, many of them 

 belonging to tlie same genus, the B oJcocerci, were caught in these 

 traps. Lanterns were suspended from the trees beneath which 

 were these tin arrangements, and below was a pan of water on 

 which was placed a little oil. That arrangement caught thou- 

 sands of moths. That is one method of controlling the enemy. 



The grove is full of l)irds. There are many bine birds, and 

 nest boxes have been put up. I do not know whether it is a good
