3- 
sulphate (involving the use of a large hypoderr:jic syringe) and 
hanging them up in places frequented by verdins these birds could 
be Killed in numbers. Orioles were also killed this way. It 
is believed that the verdin i^roblera is practically solved. 
Fifteen quarts of water nosioned with 1/2 os. of strychnine 
sulphate and exposed in crocks on the ground produced 63 birds 
in 48 hours. Of this number 17 were ilimus » 15 Toxost oma . 12 
Lophortyx , 5 Icterus . 3 Colaptes . 1 Zenaidura . 6 Geococcyx . 
and 4 Heleodytes. It is notable that 11 of the quail v/ere found 
early on the 3rd morning, after the water had partially evap- 
orated and so concentrated the poison. It appears that saccharin 
does not make strychjiined water more palatable. 
A few Toxostoma were killed with each of various formulae 
using strychnine on different kinds of grain but no satisfactory 
method of combating the species was worked out. 
Bird-lime is considered worthless in this climte* It was 
exposed on tops of posts, on wire, and on heavy cord and small 
cotton string. Straight bird-lime dries and hardens under the 
intense sun heat and v/hen mixed with •♦tree tanglefoot’’ is 
absorbed by the string and wood. On several occasions thrashers 
v/ere observed to alight v/ith impunity on limed strings and posts. 
Unfortunately Mr. Mc^tee’s letters of July 9th and 12th 
reached the v/riter subsequently to the receipt of the order 
suspending ojperations so the valuable suggestions contained in 
them could not be utilized.
