Baumé, and for summer use 1°0060 to 1°0063, or °86 to °90° 
Baumé, and the opinion was held that lime-sulphur solutions 
in general should be diluted to these limits of specific gravity 
using a Baumé hydrometer for this purpose.* American 
Agricultural authorities state that solutions of lime-sulphur 
should be diluted to contain 12 to 15 ibs. sulphur per 50 
gallons for winter use and to contain 335 to 4 ibs. sulphur 
for summer use. 
Assuming that both the above suggestions are based on 
the results of practical trials in the orchards of the two 
countries it was thought useful information would be 
afforded by correlating the results of these experiences. 
Table II has been prepared to show— 
(a) the number of gallons of water which must be added to 
one gallon of the spray so that a fluid of 1°0242 sp. 
gravity may be obtained (N.S.W. winter strength.) 
(b) the number of gallons of water which must be added to 
one gallon of the spray so that a fluid of 1°0062 sp. — 
gravity may be obtained (N.S.W. summer strength). 
(c) the number of gallons of water which must be added to 
one gallon of the spray so that the resultant fluid may 
contain 12 to 15 ibs. sulphur in 50 gallons mixture 
(American winter strength). 
(d) the number of gallons of water which must be added to 
one gallon of the spray so that the resultant fluid may 
contain 33 to 4 lbs. sulphur in 50 gallons mixture 
(American summer strength). 
This shows that in the case of the Wagga formula the 
strength is too weak for winter use according to both New 
South Wales and American recommendations, while for 
Summer strength New South Wales recommends about 
twice as much water to be added as does America.
