SOLUBLE SULPHUR COMPOUND 
Manufactured on the Pacific Coast Under Niagara Sprayer Company Patents 
As Effectual as 
THE SULPHUR SPRAY PERFECTED 
Lime-Sulphur Solution — More Convenient — Less Expensive 
Soluble Sulphur Compound 
is the old standard sulphur spray with the water 
left out, making it more convenient to handle and 
only one-sixth of the weight to pay freight 
charges on. It is a dry powder, easily dissolved 
in either cold or hot water. 
It is used In the same way as lime-sulphur solu- 
tion, is fully as effectual in every way and su- 
perior in many ways. There is no sediment; no 
grit to wear out pumps and clog nozzles; no 
freezing; no crystalization; no leakage; no loss. 
If the can is kept tightly closed it will keep in- 
definitely, and any that is left over at the end of 
the season can be used the next year. 
A 100-lb. drum of Soluble Sulphur is equal to a 
600-lb. barrel of lime-sulphur solution, saving five 
hundred pounds of freight charges, hauling and 
handling. 
Soluble Sulphur Compound is powdered by a 
fusion process, not by boiling, whereby sulphur is 
combined with soda ash, a true solvent. The re- 
sult is a perfectly soluble compound high in sul- 
phur as polysulphides. This compound is analog- 
ous in chemical form to the calcium polysulphides 
of a high-grade lime-sulphur solution. 
The sodium polysulphides are superior, for it 
should be remembered that common soda is used 
extensively in the manufacture of soaps because 
of its grease cutting property. As used in form- 
ing Soluble Sulphur Compound this grease cutting 
characteristic reinforces the primary insecticidal 
value of the sulphur, forming a superior insecti- 
cide and fungicide surpassing either material 
alone, or other combinations, such as lime-sul- 
phur. Soluble Sulphur Compound is used for the 
same purposes, on the same trees and shrubs, 
and in the same manner as lime-sulphur solution. 
Where one gallon of thirty-three degree lime-sul- 
phur solution would be used two pounds of Soluble 
Sulphur Compound is used Instead. It is simply 
sifted into the tank of water while being stirred 
or agitated, dissolves readily, and after being 
stirred for a few moments will remain in solution 
an indeflnite time. 
For estimating the amount required, those who 
have used lime-sulphur solution should order a 
one-hundred-pound drum of Soluble Sulphur in- 
stead of each fifty-gallon barrel of lime-sulphur 
solution used in the past. The amount required 
for an acre of course varies w'ith the size of trees 
and manner of using, but for average use, one 
hundred pounds of Soluble Sulphur will be suffl- 
clent for two acres of orchard.

Different From Ony Other Arsenate of Lead 
ELECTRO ARSENATE OF LEAD POWDER 
is different from any other arsenate of lead. It is 
not a paste that has been dried ancr ground, it is 
a precipitate, and is so fine that it will mix with 
water readily, will not lump, and when used as a 
dust spray will stick to the dry leaves as well as 
ordinary Arsenates of Lead when applied wet. 
It is the strongest and most effective, as well 
as the safest and easiest to use. 
By a special process which no other manufac- 
turer can employ, there is combined properly with 
lead 32% to 33% per cent arsenate oxide with less 
than one-half of one per cent freee or water solu- 
ble arsenate. Arsenic oxide is the active agent, 
and free arsenic oxide will injure the foliage if 
in excess. This gives a killing strength much 
greater than that of other brands, and conse- 
quently, much less Electro Arsenate of Lead 
Powder is needed to do the work. 
This is the original form of dry arsenate of lead 
suitable for both wet spraying and dusting, and 
the only form that is not granular or crystalline. 
There is no other as good. 
There are several distinct advantages in Electro 
Arsenate of Lead in powder form: 
You do not pay freight charges on 40 to 60 per 
cent of water, which all paste forms contain. 
It is an impalpable powder, hence there is a 
greater and more even distribution over the foli- 
age. As It does not lump, there is no clogging of 
nozzles. Every particle is of value. 
It is indestructible; age does not impair its 
value. Every one familiar with spraying knows 
the annoyance of using old pastes and that the 
lumps that remain in the tank are useless. 
This annoyance does not exist with Electro Arsen- 
ate of Lead Powder. It is always in fine mechani- 
cal condition, does not lump, is free from granula- 
tion or grit, and there is no waste.
