exposed. The tubs should be well filled. Any open spaces 

 left in the butter permit the circulation of air, and the butter 

 is more likely to absorb the woody odors from the tub.

Iii the preparation of the tub?, many of these woody odors 

 are eliminated, but it is impossible to remove all of them. The 

 heat when applied to the tub opens up the pores of the wood 

 and causes the volatile woody odors to pass off with the escaping 

 steam. When the wood is removed from the influence of the 

 steam, the pores again close, or contract, and in that way most 

 of the woody odors are removed, at least from the inner surface 

 of the tub. The remaining woody odors should not be allowed 

 to circulate inwardly through the butter by allowing empty 

 spaces inside the tub. The top surface of the butter can 

 be made to appear smooth and full by filling the tub a little 

 more than full of butter, and^then cutting the excessive amount 

 of butter off with a string. The extra butter can then be rolled 

 off, and the top appear perfectly smooth and full.
