108 AGRICULTURAL APPROPRIATION BILL, 1924, 



will be needed to clean up the counties we have already prepared. 

 That is the only work that would be possible — to finish the systematic 

 dippings and to mop up the territory in the districts that have been 

 releasetl from quarantine in order to keep the ticks in these indi- 

 vidual herds from spreading. 



Mr. Anderson. Do you mean there will not be any additional work 

 ■in any new counties under this appropriation? 



Doctor MoHij^R. There will be xeiy little if any additional new 

 territory included under the $500 .()()(). It is going to take so much 

 money to work over the territory that has already been released and 

 to do systematic dipping in the counties that are receiving educational 

 assistance at the present time that we can not go into new territory 

 in 1924. We will have to clean up the counties where we are working 

 this year in an educational way. 



Mr. Anderson. What percentage of the appropriation is used for 

 the new work each year? 



Doctor MoHLER. We have never dividied the appropriation on a 

 basis of that kind; but you can readily see that we are doing some- 

 where around 20 per cent educational work in new territory. Then 

 we are doing a little more than that amount of work in systematic 

 intensive eradication and are using the balance of the fund in 

 moi^ping up in this large number of counties that were released from 

 quarantine during the preceding year or two. 



Mr. Andp:rson. I do not just see how that can l)e. I do not see 

 how it can cost twice as much to mop up the territory that you have 

 been over the preceding year, as it does to do the new work you are 

 doing this year. 



Doctor MoHLER. For instance, last year we released, as I stated a 

 few moments ago. 49 counties as the result of the systematic dipping 

 work of 1921, that many counties being released last Deceml^er. At 

 the same time we were doing '' mopping-up ■" work in 801 counties 

 that had been cleaned up with the exception of a few individual 

 herds in each county, where the States had used their power of local 

 quarantine. Now, we have to use a great deal of care to prevent the 

 infested herds in those particular districts from spreading the ticks 

 to other adjacent districts. 



Mr. Andp:rson. I thought you said you left that to the State live 

 stock and sanitary authorities. 



Doctor MoiiLER. We leave the quarantine to the State authorities. 

 We have our men back there right along to get the last tick. What 

 we leave to the live stock and sanitary authorities is the method of 

 quarantine and the regulations to hold the animals in quarantine. 

 So you see there weie 49 of those new counties released, but at the 

 same time we were working in HOI counties after their release from 

 quarantine, because there was some infection left behind. But we 

 have never figured out and never divided uj) the work so as to know 

 just how mucli it has cost us to do advance educational work, uov to 

 do the work in the second line treni'hes where the 14-day systematic 

 dippings occur, nor have we figured out the proportional cost of 

 mopping-u|) woik which is the final work before the territory is 

 entirely cleaned up of the tick. 



Mr. Anderson. \{)u must have to go back to .some of this terri- 

 tory for more than a year, if that is the case.
