THE MONTHLY BULLETIN. 



This corresponds to 1% to 2 ounces of the liquid carbon disulphid when 

 mixed in the air of a fairly large burrow. "With smaller burrows some 

 of the carbon disulphid is doubtless wasted, but burrows probably 

 seldom occur of sufficient size to justify using larger quantities. It 

 seems clear that the usual procedure of 1\ to 2 ounces is likely to be 

 the most effective in the sense that it will kill squirrels at the minimum 

 expense per animal. With the possible exception of the arsenic com- 

 pound mentioned above it is extremely unlikely that any of the other 

 substances experimented with can effectively displace carbon disulphid, 

 but that carbon disulphid should be used in connection with some form 

 of pump which will insure maximum dispersion of the gas throughout 

 the burrow. 



AMMUNITION USED BY 4-MINUTE MEN, DURING "SQUIRREL WEEK," 

 APRIL 29th-MAY 4th, 1918. 



The State Commission of Horticulture, through its Rodent Control Division, is 

 endeavoring to bring together all organizations that can be of assistance in squirrel 

 control. Why? Because it always takes continual work, concerted action, sys- 

 tematic effort and community co-operation to accomplish the best results. 



The BEST squirrel is the dead squirrel. 



On an average, ground squirrel destruction to agricultural crops in California 

 amounts to $1.00 per acre. In instances it amounts to as high as $10 per acre. 



The Hotel California board bill for ground squirrels in 1917, estimated by the 

 United States Biological Survey, was $30,000,000— yet unpaid. 



The ground squirrel is admitted in many counties to be its worst crop pest. 



Are you not willing then to give your whole-hearted support to this state-wide 

 movement to KILL THE SQUIRREL? 



We farmers pay higher taxes to the ground squirrel than to the assessor. 



The value of food products destroyed by the ground squirrel in 1917 exceeds the 

 gold productions by eight millions. 



There are 100,000,000 acres in California. Each one, on the average, has a 

 ground squirrel who does not live on thin air. If each one cost one cent in two 

 weeks to feed, we pay an annual board bill of $30,000,000. That will keep 40,000 

 families in food for a year. 



The other fellow knows that your squirrels are worse than his. Are you in the 

 same boat? 



Don't let George do it. He will fail you every time. 

 The squirrel does not recognize daylight saving. He uses it all. 

 He harvests crops as soon as they are put in the ground and keeps at 'em. We 

 must keep at him. 



He preys on our crops in countless hordes. He fills the ranks of the killed in 

 true military fashion. 



We hear from one end of California to the other — lost 20 acres of almonds ; no 

 grain for the first six rounds in my 160 of barley ; 7000 young trees destroyed 

 before the buds came ; ditch washout cost us $2000 ; 256 barrels of oil down the 

 wash over night. Can we let this continue? Not if we have good reason. 



Why hesitate? We can get 'em. How? Poison 'em, gas 'em, drown 'em, shoot 

 'em, trap 'em, submarine 'em. 



We must work as efficiently as the ground squirrel in order to combat him 

 effectively. 



You do not know how to do it? Well, just call for advice and assistance from 

 the State Rodent Control Division, State Commission of Horticulture, at Sacramento, 

 and from your local county horticultural commissioner. 



There are a number of ways of killing the ground squirrels. Either of these 

 organizations will tell you the best method to suit conditions at the time.
