" Ue\r Siu,— I had no guarantee as to the purity of this cake ; I am 
afraid we agriculturists as a class are careless in this respect. — Yours truly, 
" Ed. BEOUCillALL."

" This is the worst cake I have seen for a long time. It has no right to 
be called linseed-cake at all. "J. Augustus Voelceek." 
When urged to communicate the names of the manufacturers 
and others concerned in supplying farmers with such an article, 
Mr. Jenks wrote : — 
"December 1, 1SS8. 
" Dear Sir, — "With respect to your inquiry as to linseed-cake No. 1512, 
the agents i'rom whom I bought the cake communicated with the maker. 
They at once asked me to return cake, they paying carriage and sending 
me another lot of cake, of which I enclose you a sample for analysis. 
"Should your report of this lot be favourable, out of sympathy for the 
agent, who in these cases suffers from the publicity although often quite 
blameless, I do not feel inclined to proceed further in the matter — Faith- 
fully yours, " Thos. Jexks." 
A sample of the new lot of cake was accordingly analysed, 
with the following result : —
