In 1914 grove A was sprayed as fol¬ 
lows: March, oil spray; April, lime-sul¬ 
phur; June, lime-sulphur ; July, lime-sul¬ 
phur; August, oil and soluble sulphur; 
October, lime-sulphur; December, oil. 
In 1914 grove B was sprayed as fol- . 
lows: February, Bordeaux; March, Bor¬ 
deaux; April 3, soluble sulphur; April 22, 
soluble sulphur; Miay 8, soluble sulphur 
and oil; June, lime-sulphur; July, lime- 
sulphur; August, soluble sulphur and oil; 
October, lime-sulphur; December, oil. 
Note —Grove A was sprayed only once 
in April, while grove B was sprayed twice 
in the same period. This is probably due 
to the fact that on grove A lime-sulphur 
was used, while on grove B soluble sul¬ 
phur was employed as a rust mite and 
scab preventative. I understand that this 
agrees with Mr. Mother's experience. On 
the other hand, the soluble sulphur makes 
a very effective combination when mixed 
with an oil spray. 
THE ORIGINAL OR PRIMARY CAUSE OF MAL DE GOMA 
Dr. T. G. Julian, 
I do not approach this subject as an 
iconoclast; to destroy and pull down any 
previously accepted theory or explode any 
notion or opinion that anyone may have 
entertained as to remedies, how and when 
to cure, but ask you to add to or build one 
step farther as the primarily immediately 
contingent to what we see in the mani- 
Clearwater, Fla. 
festations of this dreaded disease, no cure 
or remedy, but the cause. 
The only way I can ask you to forbear 
and appreciate how I arrived at my con¬ 
clusions is to outline a history of my ex¬ 
perience, as some are pleased to call ‘Jul¬ 
ian’s Theory/ and fifteen years ago it 
was ‘Julian’s Theory’ and I will relate
