Fertilizer for Sweet Potatoes 
What kind of commercial fertilizer do 
Maryland gardeners use on their sweet 
potatoes? IIow applied, and how much 
to ilie square rod, or per acre? ir. i*. it. 
I toby, Ill. 
The treatment of the land for the sweet 
potato crop varies with different growers 
and in different conditions of the soil. 
The two counties of Virginia on the east 
side of the ('hesapeake grow sweety pota¬ 
toes very largely, and in rather a differ¬ 
ent manner from our growers. There, 
during the Winter, they rake up the pine 
needles and rotten trash from the pine 
woods and spread this material on the 
land intended for sweet potatoes in the 
■Spring, and plow it under. Then in 
Spring they lay off the rows and add 
commercial fertilizer, and make the lists 
on which the plants are set. Our growers 
here seldom if ever haul and spread the 
trash from the forest. Our best growers 
spread in the Spring and plow under a 
light broadcast, application of stable ma¬ 
nure. Then they use a fertilizer at rate 
of about 500 lbs. an acre in the furrows 
on which the ridges are made for setting 
te plants. t)n sandy soil, which we have 
here, and which is best for sweet potatoes, 
the fertilizer used after a broadcast of 
manure need not contain much nitrogen. 
A fertilizer containing 2 per cent am¬ 
monia, S per cent of phosphoric acid and 
4 per cent: potash from sulphate will make 
a good crop. When no coal of manure 
is used the fertilizer should contain ‘5 per 
cent ammonia; that is. about 2..”0 per 
cent nitrogen. The fertilizer men always 
put the nitrogen on the sacks in form of 
ammonia, as it makes the figures look 
larger. Ammonia carries about So per 
cent nitrogen. In fact, the fertilizer mix¬ 
tures seldom contain any ammonia at all. 
but do contain organic nitrogen, which in 
the soil passes into ammonia and thence 
to a nitrate before plants use it.

A Discussion of the J. H. Hale Peach 
Seeing the picture of the Hale peach, 
and reading the editor’s note in connec¬ 
tion with the article by I., C*. Williams, 
page 1402, prompts me to give my experi¬ 
ence with this “liver-rated" peneh. When 
it was first let loose upon the public, sev¬ 
eral years ago, 1 bought and set out about 
20 trees. I find they are a slow and poor 
grower, never making but half the size of 
tree an Elberta will. No matter how 
you feed or care for them, I find when 
other varieties have a good crop of nice 
sized fruit, the Hale will he about the 
size of a black walnut with the shell on. 
When other varieties are somewhat shy 
of a crop, the Hale will be very shy, but 
the fruit will be ns large a- a croquet, 
bull! In other words. T find the Hale an 
unreliable hearer, or one year a fair crop 
and fruit small, another year a shy crop 
ami fruit. e..rra large. Eight alongside of 
Elberta, it "can’t hold a fiiulle to it." 
As a result of my experience 1 have dug 
out all my Hales and planted Elberta. 
When it conies to quality, then that is 
another story, For n yellow variety if 
cannot he beaten for quality; it is al«o 
very firm. I believe you could ship the 
fruit in barrel lots, they aim so firm, and 
I find they will stay on the tree longer 
than other kinds beloro getting over ripe. 
For a person who wants a high-quality 
yellow peach for private use. I don’t think 
the Hale can he beaten, but for a Com¬ 
mercial proposition, never. 
While I arn writing about my experi¬ 
ence with the TTule peach, I would also 
like to say I tried that "new stuff with 
the long name" fparadieldorohenzine 1 for 
peach borers. T’sed it rather late Octo¬ 
ber around trees about 10 years old. I 
have just removed the dirt from around 
these few trees, and find the borers dead. 
Yes. nil of them. too. Hut it is some job 
ruing around these trees, smoothing off 
the soil, putting the stuff around “just 
so." an ounce to a tree, covering and 
hanking again to hold ttie gas in. I don’t 
know but whet, one could dig them out 
with the knife about as quickly with less 
exneuse. A. L. VREELAND.

Greenhouse White Fly 
Will you tell me whnt will kill white 
llir-. on plains? ft. Nr. c. 
Tf the insect referred to is the green¬ 
house white fly. it is not easily controlled, 
and may be unite troublesome. The adults 
have four wings, covered with a whitish 
powder, and are active in flying about. 
The young are flattened and oval in 
shape. The insects are found on the 
under side of the leaves, where they suek 
the juices of the plant, and injure its vi¬ 
tality very seriously. The most effective 
remedy is fumigation with hydrocyanic 
m id ens, 1ml this is too dangerous for use 
with house plants. Benefit will be derived 
from spraying with whale-oil soap. 1 Vj 
oz. dissolved in 1 gal. of water. The 
spray must he usd persistently and re¬ 
peatedly. ns some of the active adults al¬ 
ways get. away. The pest is sometimes a 
very serious trouble iu the window gar¬
