dug nearly or quite a foot. Get together 
heaps of small stones, broken rocks, etc., and 
all the sifted coal ciuders that can be had. 
Cinders, or scoria, from the blacksmith’s or a 
foundry are excellent, and may be had for the 
hauling. If it is possible to get plenty of these 
there will be no need to bother with the stones. 
If there should be a pottery in Felicity, (and 
what would Felicity be without one?) the pro¬ 
prietor will be glad to have you remove the 
heaps of broken material that arc always in 
his way, and you will have Becured one of the 
cheapest as well as best of materials for a good 
rural walk. With either one or all of the 
above materials you can make a durable 
one. The best as well as the heaviest 
walks and drives wc ever made were con¬ 
structed of the refuse of an iron mine—reul 
road metal. Anything, in fact, which is hard 
and angular, will answer the purpose. A good 
road canuot be made ol round stones. 
Whatever material is used put the largest 
pieces at the bottom and the smallest on the 
top. The bottom of the walk should not be 
flat, but lowest at the 6ides ; in other words, 
slightly arched. Having put a layer of ma¬ 
terial on the bottom, roll it down with a gar¬ 
den roller, if you have one, or in 6ome other 
way make it solid. Theu put on another layer 
is quite appropriate to grow young pigs with¬ 
out some more nitrogenous food mixed with it. 
The Cow-pea, at the South, is excellent to feed 
with the sweet potato, as it contains just what 
the potato lacks. Feeders should study how 
to mix foods of various qualities together, and 
not try to find a single food for general feed¬ 
ing, for no one food contains all the qualities 
to satisfy the wants of the animal. 
Grafting Evergreens. 
A Subscriber, Nashville, Ohio, asks how to 
graft evergreens, 
-Ans.—T o graft evergreens under any circum¬ 
stances is Dot easy. Out-of-doors it is espe¬ 
cially hard on account of sudden changes of 
weather, etc. A covering of oil paper will help 
to protect the graft. In a small greenhouse or 
under a sash the operation is easier, although 
fraught with considerable difficulty even then. 
The difficulty does not lie so much in the mere 
operation of cutting and inserting the cion into 
the graft, as in the selection of proper stock 
and general care of the grafted plant until it 
has passed a certain critical peri od. The tem¬ 
perature must be kept warm aDd very even. 
A sash within a green-house is therefore often 
used. 
lu regard to selecting a suitable stock for the 
different varieties of evergreens, the following 
rule may be considered established. Use only 
such 6toeks as are closely allied by nature to 
the exon. In moat cases, the stock should 
belong to the same sort. For instance, for 
such evergreens as the varieties of Norway 
Spruce, Hemlock, Arbor-vitas, Juniper (Red 
Cedar), etc., the same Norway Spruce, Hem¬ 
lock, etc., must be used as stocks. The two¬ 
leaved, three-leaved Pines and five-leaved Pines 
whether White, Scotch or Mughus—must be 
used as stocks for varieties belonging to their 
lespcctive divisions. There are, doubtless, 
Beeuilng exceptions to this rule, as wheu we 
find the Retinosporas of Japan grafting readily 
and permanently on our Arbor-yit®s, but the 
Retinosporas would, we feel confident, be 
called Arbor-vines if they were American-born 
instead of Asiatic origin. Jn short, it would 
seem that the value of these affinities between 
plains in the relation of stock a d cion is not 
sufficiently recognized^u our botanical classi¬ 
fication. 
W. H., Adamsville—one of 14 in 14 States— 
asks. 1, are any fertilizing quaJitiea lost by 
burniug; 2, the best early tomato ; S, the best 
sweet corn; 4, the best incubator; 5, what 
degree of temperature is best adapted to the 
preservation of fruit; 6. will hens do well 
confined to a yard; 7, will cabbage thrive in 
wet land; 8, will Paris-green injure potato 
vines ? 
Ans.— 1. Yes, nitrogen is lost by burning as 
well as phosphorus and sulphur in minute 
quantities; phosphorus, chlorine, sulphur, 
potassium, sodium, lime, magnesium, etc., are 
left as ash constituents. 2. There is no ’* beet” 
early tomato. What is earliest with us may 
not be earliest with you. We have found the 
u Little Gem” the earliest. But it is a poor 
thing. Conqueror is considered an early to¬ 
mato. Hathaway’s Excelsior is early and 
good. Hubbard's Curled-leaf is also early aDd 
good. The leaves curl up as if the plant were 
suffering for water. 3, Triumph is early and 
excellent. Early Minnesota is esteemed by 
many market gardeners as at the present lime 
the earliest and best—that is of very early 
varities. 4. Halstead's is as good as any we 
know of. 5. Just above freezing. 6. Yes, if 
given all the kinds of food they need; if the 
houses and ruus be kept scrupulously clean; 
if not more than ten are confined in an area of 
400 square feet. «, No. Laud, to grow fine 
cabbages must he well-diaiued. Much de¬ 
pends upon the season, but, as a rule, flue crops 
can be produced on any land whether muck, 
clay, saud, if well prepared aud manured. But 
it must not be icel. 8. Yes; if used too stroug. 
One pound of pure Green to 40 of flour or 
plaster—is about the right strength, though it 
has proved quite effectual when diluted very 
much more.

the material beneath. Avoid the too common 
mistake of making the walk too high. The 
grass edge or border at the sides should be not 
less than an inch above the sides of the walk. 
Fiuish the surface with a very slight curve, or 
just enough to carry surface water to the sides. 
Walks that are rouuded up too much, arc not 
only unpleasant and disagreeable to walk upon, 
but decidedly hurtful, especially to young 
people and children. Unless the walks are in 
some parts steep, gutters will uot be needed. 
As soon as the surface has been laid, water 
it well with a watering pot having a “ rose," 
and then pass the roller over it till it becomes 
firm ; or it can be rolled partly now, and gone 
over again after the first rain. This rolling 
will develop some inequalities aud depressions 
which must be carefully filled, and rolled 
again. Go over the work in this way, and 
contiuue to remedy the defects as they appear, 
till you can look at it at last with the eye of an 
artist, and say it ib well done; aud may all the 
ladies in Felicity do likewise. A statement of 
what material can be had and the nature of the 
soil would make it much more easy to answer 
6uck questions. 
Sweet Potatoes vs. Corn for Hogs. 
J. W. 8., Owensboro, Ky ., asks the relative 
value of sweet potatoes and corn for fatttning 
hogs. 
Ans. —We have seen but one analysis of 
sweet potatoes, and that by Dr. A. R. Ledoux, 
of the N. C. Experiment Station. The sweet 
potato has 6ligtuly less water than, the Irish 
potato aud also less albuminoids, but is richer 
in glucose or sugar. We give a table of the 
digestible constituents of the sweet potato, 
Irish potato, Indian corn and cotton seed cake.

Irish potato.. ' 2.' 
Indian corn...” j 7.; 
Cotton-seed cake (decorticated). ’ 3 1.1 
This table gives a full understaudiog of the 
comparative value of both kinds of potatoes as 
compared with corn and cotton-seed cake. We 
give cotton-seed cuke, because it appears that 
the sweet potato is deficient iu albumiuoids or 
muscle-forming matter, aud cotton-seed is very 
rich in this element. And as the sweet potato 
aud cotton-seed grow together, a little of the. 
latter should bo fed with the former to make a 
well-balanced food. The sweet potato has only 
one of albuminoids to IS 6-10 of carbohydrates 
or fat-forming food whilst the Irish potato has 
one to 10 6-10, and corn about the same. Lean 
shotes of 100 or more pounds’ weight may be 
fattened properly upon sweet potatoes, because 
they only need fat laid on to fit them for 
slaughter: but they have not muscle-forming 
matter enough to grow pigs properly ; yet, if 
a small proportion of cotton-seed cake is given 
with sweet potatoes, the food Is excellent for 
growiug or fattening pigs. Four pouuds of 
boiled cotton-sced or two pouuds of decorti¬ 
cated cake, fed with one bushel of sweet pota¬ 
toes, will make a well-balanced ration for 
hogs. Jt will be seen that 400 pounds of sweet 
potatoes are only about equal to 100 pounds of 
corn. But the sugar of sweet potatoes is a 
little more fattening than the same weight of 
starch in com, Neither the potato nor corn
