Experiments on Wheat and Grass. 
A Plew and Simple Set of Fertilizers, Costing only S5 per set, 
Adapted for Testing any Soil for Deficiency in the more 
Important Elements of Plant Food, 
“COMPLETE MANURE SET, ” 
Designed for Those who Require a Set Requiring the Least Possible Care 
and Trouble in its Use. 
This set consists of only four bays of uniformnoeight, (50 lbs|each), requiring no mixing or further preparation, to he 
applied on four alternate strips of Wheat, Grass, or other Crop. May he applied in Drill, Broadcast, or as a Top-dressing by 
liand or machine. 
Bag A, SO lbs., complete manure, containing the main in- i Bag B, 50 lbs., same as Bag A, with nitrogen omitted, 
gredicnls in about the same proportion as, hut in far more Bag C, 50 lbs., “ “ “ phos. acid “ 
soluble and concentrated form than, stable manure. > Bag 1 ), 50 lbs., “ “ “ potash 
The results from tlies efotir bags applied in four alternate strips will, during an average good growing season, indicate 
which one or more of the important ingredients Nitrogen, Phosphoric Acid, and Potash is detioient in the soil for growing 
the crop experimented upon. Full directions accompany each set. Any ordinary farm-hand can apply them. To eacli bag 
is attached a tag giving the number of pounds of eacli ingredient furnished, and the source from which obtained, with 
guaranteed compositi >n. Bags A, B, C, and D, will be put up in a large bag as “ Complete Manure Set.” 
Price, per set, delivered to cars or boat at New York, $5. Price, with plaster omitted, requiring to be reduced in strength 
by mixing with a diviser before use, $4.50. Five sets (ready mixed), will he sent to one address in one shipment on receipt 
of $22.50. Tlie endorsement of this plan of experiments by nearly all the Agricultural Press, Agricultural Colleges, and 
Stations, as well as by many prominent agriculturists, lias encouraged us to extend every facility in our power, including 
pamphlets and other descriptive matter calculated to insure its success. 
Set A, including pamphlet on “ Farm Experiments,” written by Prof. W. O. Atwater, and blanks furnished as hereto¬ 
fore, at Any one or more single bags of Set A. and also of the extras (for full description and. prices see American 
Agriculturist for April and May, 1878), furnished in connection with Complete Manure Set, at published prices. By com¬ 
bining with the Complete Manure Set either one of Bags I„ II., and III., of Set A, the experiments may be adapted to any 
crop on almost any soil. Address,

The Chamberlin Screw Stump Machine, 
' after 10 years test, has proved its 
superiority over all others, bv its 
great exhibition of strength'and 
durability, combined with cheap¬ 
ness and ease in nulling all classes of 
stumps. The Company’s challenge 
of £1000 for a stump machine which 
would excel theirs, has stood since 
1867 without being taken. They build 
6 different sizes of machines, to pull 
all kind9 of stumps. They make 
Subsoilers and Ditching Plows. For

WHEAT. 
A Great Instructive Experiment 
will be made this Fall to prove whether or not tlie lack of 
BONE 
in the soil is tlie cause of poor yields of Wheat and failure 
of Grass Crops. The application to wheat and grass of the 
Pure, Clean, Raw, Odorless, and Fine Ground Bone known 
as Premium Bone, has so clearly proved that Bone element 
is the great need, that we believe Farmers should make a 
wide extended experiment on a great variety of soils 
throughout the Union. 
Out of what is the grain of wheat made? What are the 
proportion of its elements? What are they?—Wheat is 
made out of Atmosphere and mineral or soil elements, in 
the following proportions: 
Atmosphere (free to man). 19,000 parts. 
Phosphoric Acid iBone element deficient in all 
soils showing exhaustion). 498 “ 
Potash (seldom deficient except on soils under 
culture for a long period of years). 237 “ 
Magnesia (enough in the sml for a long period 
of years). 120 “ 
Soda (common salt element). 91 “ 
Lime (in bone in its purest state). 28 “ 
Silica (sand). 16 “ 
Peroxide of Iron. 7 “ 
Sulphuric Acid. 3 “ 
20,000 parts. 
19 parts of wheat is atmosphere. 1 part of wheat is 
mineral or soil element. Si of the mineral elements is 
Phosphoric Arid. Every t"n of Premium Bone contains560 
lbs. Phosphoric Acid. Every bushel of wheat contains 3-5 
of a lb. of Phosphoric Acid. A ton of Premium Bone con¬ 
tains enough Phosphoric Acid to supplj 933 bus. wheat, and 
a ton of Premium Bone being made from Raw Bones (not 
steamed or burned) supplies to wheat 100 lbs. Ammonia. 
Unless land ha9 been cropped a very long time, there is no 
necessity for supplying anything outside of common ma¬ 
nure, except Premium Bone. Farmers, write at once for 
terms for wheat seeding to
