New YorkK AGRICULTURAL HXXPERIMENT STATION. 345 
SUMMARY OF RESULTS. 
These experiments, although including but a few trees, are 
sufficiently extensive to indicate final results. No attempt was 
made 10 compare the cost of making the different mixtures as 
none of them are expensive. The principal difference in the 
cost of making lies in the apparatus required and the amount 
of boiling necessary. Where boiling can be avoided considerable 
inconvenience and expense is saved. 
Comparing the resin washes, the one made after the Station 
formula proved as effectual in killing the scale as the other, 
did not injure the trees when applied before the leaf buds burst, 
and can be made more conveniently and economically, as it does 
not require boiling and the cost of the ammonia is slight. The 
casein has a slight advantage over the resin in adhesive quali- 
ties, but it is probably not sufficient to warrant the additional 
expense. 
None of the compounds tested gave any better results than 
the lime-sulphur-salt and bordeaux mixture, and this has the 
additional advantage, which is of much practical importance, of 
combining both the insecticidal and fungicidal properties. By 
combining the two, therefore, the necessity of making an extra 
treatment for the scale is avoided. 
DISCUSSION OF RESULTS AND CONCLUSIONS. 
The experiments recorded in this bulletin represents but one 
season’s work and, therefore, should be considered as prelim- 
inary. Any conclusions that may be based upon such experi- 
ments are necessarily provisional, and this is all that is claimed 
in this case. It may be noted, however, that, in general, the 
results in the East with the lime-sulphur-salt wash have been 
favorable, and as this is the case with the present experiments, 
they bear out results already obtained. 
As stated on a previous page, the wash has proven a satis- 
factory remedy in California. Its power to destroy the scale 
there has been demonstrated. It now remains to determine 
whether this can be said of it under our eastern climatic condi-
