the time tlie eliestinit blossoius, a little moth hijs an egg on the 

 yonng frnit. The egg liatehes and a little worm bnrroAvs its 

 way into Uni bnrr. It seems to prefer living on the burr rather 

 than the nnt. This view shows what I have called the "little'' 

 bnrr worm. Here it is. It lives normally in the bnrr. Occa- 

 sionally it eats into the nut, but it does not like the nnt, bnt 

 leaves an ngly hole and the nut afterwards frequently moulds. 



This shows the adult moth, the Holcocera Soherii. It is very 

 similar to the ITolcoccra (jlandulata, but, according to Kear- 

 foot, of Montclair, New Jersey, it should be called a distinct 

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

 one of the Avorst enemies. Tliere are two shown 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, l>ut 

 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 Avhen 

 the burr is removed the cocoon is removed; but I have not been 

 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 Ihe injury done. Tlie 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 immediatel}'^ or used, 

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

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

 entirely. In ihis case this nnt shown has cracked 0]pen, and 

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

 some of them resemble very much the ordinary bread mould. 



Insect traps were made by Mr. Sober in 1910 and placed 

 throughout th(^ grove, and thousands of moths, many of them 

 belonging to the same genus, fho. Holcocera, were caught in these 

 tra]is. Lanterns Avere suspended from the trees beneath which 

 were tlicse tin arrangements, and beloAV was a pan of Avater on 

 AA'hich Avas placed a little oil. That arrangement caught thou- 

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



The grove is full of birds. There are many blue birds, and 

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