Transferring the Starters. — The starter, to be successful, must be 

 transferred daily and some inexpensive transferrer must be devised 

 to meet all requirements. The operator, in order to make successful 

 transfers, must have something that will convey the proper amount, 

 be easy of sterilization, have relative freedom from contamination, and 

 convenience in handling. A vial with a wire handle, a piece of cloth 

 wound loosely about a wire handle, or a small amount of cotton wound 

 firmly about a wire, as shown in Fig. 3, are some transferring tools 

 easily made, and fully meeting all requirements. Of these transferrers, 

 the latter seems best fitted for all practical purposes. It is easily 

 constructed by taking a wire which has been made rough on one end 



Fig. 7. 



and some loose cotton batting as shown in Fig. 4. The cotton is wound 

 firmly around the wire by holding between the thumb and first and 

 second fingers, as shown in Fig. 5. 



The transferrer should be placed in the milk before sterilization be- 

 ,gins and should never be removed until ready for the transfer. 



After inoculation and loppering, a safe transfer may be made by 

 removing the plugs of both bottles and lifting this transferrer very 

 carefully from the loppered milk and placing it in the sterile milk, 

 care hcing taken not to alloio the swat) to came in contact icith any- 

 thing during the operation. The plugs should not be transferred from 

 one bottle to another, but should be removed as shown in Figs. 6 and 7.
