Mr. Jack Peters here quoted from mem¬ 
ory which had been submitted to him by 
circular, and explained that he should 
have brought the circular with him for 
definite verification. 
Capt. Rose, State Chemist, discussed 
the question. He explaned how the val¬ 
uations in the Quarterly Bulletin were 
made up. The quotations were gotten 
from the fertilizer houses in the State. In 
addition to this, the quotations were ob¬ 
tained from Savannah and New York 
houses, the cost of transportation added 
to the quotations given to the out-of- 
State houses. Then an average of the 
State prices and the delivery prices of the 
out-of-State houses was calculated. 
Capt. Rose then called attention to the 
fact that the Florida grower was able to 
secure fertilizer material just as cheaply 
as could be secured anywhere else, and 
that they had further advantage of be¬ 
ing able to buy unmixed chemicals. In 
former years it was impossible to buy 
anything but mixed goods. 
Question 30. Is there any danger, or 
is it detrimental to a young grove to 
grow sweet potatoes between rows for 
the first year? 
Mr. Jack Peters replied that sweet po¬ 
tatoes can be grown splendidly in a young 
citrus grove. He stated it was wise to 
keep at least six feet from the tree, and 
then make as many rows as the middles 
will permit. The sweet potatoes may be 
dug at any time they are marketable. 
After the sweet potatoes have been taken 
off, the land should be sown to some 
legume. This would replace the nitro¬ 
gen taken out by the sweet potatoes. 
Mr. Condon asked about salamanders 
eating off the young trees when sweet 
potatoes are planted in the grove. There 
is some danger from this source; however, 
by means of proper trapping, and by 
shooting the salamanders, no great trouble 
should be experienced. 
Mr. Lamont advises to plant only two 
rows in the middles between the citrus 
rows. 
Question 31. Does dynamiting citrus 
trees help to overcome any of the dis¬ 
eases or insects to which they are sub¬ 
ject? 
President Hume explained the central 
idea, the general question was not wheth¬ 
er the dynamite would kill the insects 
and cure the diseases, but whether the 
effect on the trees was such that the dis¬ 
eases and insects would be less destruc¬ 
tive. 
Mr. Robinson, of Terra Ceia, stated 
that he had 'used dynamite under his 
trees. He inserted the amount of dyna¬ 
mite necessary to loosen up the ground 
around the tree without blowing the tree 
out of the ground. Where a tree was 
tilted over by the force of the dynamite, 
the tree was placed back in its proper 
position. He put the dynamite down 
about two feet, and used about a half of a 
stick right under the tree, at other times 
where the tree did not seem to need shak¬ 
ing up the dynamite was placed in the 
middle. Mr. Robinson thinks it a good 
plan to use dynamite on compact soils. 
Senator Darby used it on his hammock 
land at Rockledge, and comparatively it 
is giving good results. 
Question 32. Is there any method by
