No. 4.—BureGunpy MIxTuRE. 
Sulphate of Copper .. 4Ibs. 
Carbonate of Soda (Washing Soda) ..  5lbs. 
Water 6s .. 22gals. 
(a.) Dissolve Bieene. as in Ramdcanse Mixture. 
(b.) Dissolve the carbonate of soda ; mixing the two solutions 
gradually, stirring the while. Make up the quantity with water. 
A gelatinous hydrocarbonate of copper is formed. In W.A. it is 
easier prepared than Bordeaux Mixture, good lime free of grit 
being scarce. Adheres better to foliage than does Bordeaux 
mixture, its only drawback is being a little more expensive. The 
precipitate, which is bluish green, remains longer in suspension in 
the liquid than does Bordeaux Mixture. Molasses, $lb. to the quan- 
tity above added a few hours before using, makes it more adhesive ; 
sucrate as well as hydrocarbonate of copper being formed which 
is dark red, very light and very adhesive. For summer formula 
use 4: 5:44. Do not add Paris Green to this as the soda dissolves 
the arsenate and would cause leaf burn. 
The addition of Paris Green or of arsenate of lead 2o0zs. to 
every 22 gallons of the spray will get at nibbling insects as well. 
These two sprays should only be mixed together when ready 
for use, as they deteriorate in keeping and become less adhesive. 
No. 5.—SvuLpHATE or Tron Swas. 
Sulphate of Iron (Copperas) soe ... 25lbs. 
Sulphuric Acid Sas adr isis .. Tbs. 
Warm Water oa ti ah -» 10gal. 
Pour the sulphuric acid over the copperas, and then add the 
water. No metallic vessel should be used ; an open barrel treated 
inside and out with paraffin wax or tar is the best. Apply with a 
swab made of binder twine or of woollen rag, no metal to be used. 
After pruning, just before the buds open, the copperas is not in- 
dispensable. A 10 to 12 per cent. solution of sulphuric acid (six 
to seven quarts of acid in 25 gallons water) is at times used as a 
substitute. The acid solution may also be applied as a spray from 
a pump fixed on a barrel drawn on a sledge or on a spring cart. 
The pump and nozzle should be thoroughly washed, every day, im- 
mediately the spraying is stopped. It is a good plan to have the 
pump annealed with lead or lead galvanised.
