STATEMENT OF AUTHORSHIP 
This is the second bulletin published jointly by the depart- 
ment and several State experiment stations to report results 
of cooperative soft-pork investigations. The first publica- 
tion, Department Bulletin 1407, entitled " Some Results of 
Soft-Pork Investigations," was issued in April, 1926. The 
reader is referred to the introductory pages of that bulletin 
for a detailed presentation and discussion of the various 
aspects and phases of the soft-pork problem and of the 
methods employed in the cooperative study. In this bulle- 
tin only sufficient explanation relating to the problem and 
methods is given to furnish a background for the reader who 
has not read Department Bulletin 1407. While the investi- 
gations are being continued it is the purpose to present in 
detail the data and conclusions which have been agreed on 
for issuance by the cooperating institutions since the first 
bulletin was completed. The results reported were obtained 
under the direction of the following:
