132 Quarterly Report of the Chemical Committee, March 1892. 
Dr. Voelcker’s analysis of the sample gave the following 
results : — 
It will be observed, on comparing the two results, that they do 
not show any very great divergence, and the manure might be con- 
sidered as nearly coming up to the guarantee given. 
It is necessary, however, to point out the misleading nature of 
the guarantee. It is one which really amounts to nothing, the 
phosphates and ammonia being grouped along with the organic 
matter, &c., whereas the results of Dr. Voelcker’s analysis show 
these constituents to be present in but small quantity. 
A manure containing so little fertilising matter as the sample 
examined is not worth a third of the price asked for it. 
10. Adulteration of Manilla Hemp . — It has been brought before 
the notice of the Committee that adulteration of Manilla hemp is 
being extensively practised, and that binder twine is being fre- 
quently sold under the name “Best Manilla,” although it contains 
none or very little genuine Manilla fibre. 
As the use of twine for sheaf- binding and similar purposes is 
likely to increase, purchasers are advised to be careful to obtain a 
guarantee of the twine being “ Manilla fibre.” 
The Committee in conclusion would again impress on Members 
of the Society the extreme importance of stipulating with the 
vendors of feeding-stuff’s for a written guarantee at the time of 
purchase, to be repeated on the invoice, that the feeding-stuflf bought 
is pure, and will be delivered in good condition for feeding purposes.

CONSULTING ENTOMOLOGIST, 
March, 1892. 
During the past three months there has been the customary amount 
of application, but until lately this has been mainly in continuation 
of observations of last season’s attacks, or in the form of inquiry as to 
measures of timely prevention of attacks before spring developments.
