Pro forma. — A double action patent I'ouritain 

 pump in cast iron, cast iron suction or breeches 

 piece for five-inch piping, with cast iron standard 

 and wrought iron fire engine leverage, and wood 

 cross pieces, having brass expresser buckets, with 

 butterfiy valves, leather conncctois in metal rings, 

 screw bolts, metal lower boxes and spindle valves, 

 wrought iron rods, bolts, nuls, puis and l<eys, 

 complete, to power No. 10* — £18 lOd.

The above machines are built expressly for 

 manual labor ; they are very simple in ilieir con- 

 struction, but of course the labor, whether sharp 

 or slow, will supply a larger or less delivery.

ANALYSIS OF PRAIRIE SOILS FROM BIONT- 

 GOMERY COUNTY, (ALA.) 



By Professor Shepard. 



From tlie Sontiiern A^rioiltiirist. 



Three specimens of prairie soil were brought 

 to me Jbr examination by Dr. C. Bellintrer, of 

 Alabama. They were taken from a [)lantation 

 seven or eight miles in a south-easterly direction 

 from ihe town of Montgomery. 



No. 1 is a fine black mould Irom timbered land, 

 which was situated rather low. It, produces cot- 

 ton to advantage when 'he season proves dry, and 

 is well adapted to other crops, whether the sum- 

 mer is dry or wet. Ji varies in depth from six li'.et' 

 to one inch. 



No. 2 is a fine snufi-colored soil, and is the best 

 land lor cotton in the country. Small grain (oats, 

 wheat and rye,) and com sometimes do well upon 

 it also ; but it is less suitable lor these crops tiian 

 No. 1. It varies in depth from one inch to ten feet. 



No. 3. This soil is called "bald prairie." In 

 color it is grayish white, with a slight tinge of yel- 

 low, or fawn. It coheres into email lumps, which

 about six thousand three hundred gallons per hoiu-.

 about ten thousand five hundred gallons per hour.

 about twenty-five thousand two hundred gallons per 

 hour. 



are variegated from the presence of white calca- 

 reous spots — the remains of shells. It is consider- 

 ed as jioor land, thouirh it answers for small grain 

 and grasses tolerably well. It is not adapted to 

 the cotton crop. 



No. 3 Ibrms the underlie of No. 1 and No. 2, 

 and is iiseif found resting upon the "rotten lime- 

 stone." 



Equal weights of the above soils were tho- 

 roughly htmiected with pure water, when their 

 weights had increased from 100 to 



177 ----- in No. 1. 

 157 - - - - - in No. 2. 



162 - - - - - in No. 3. 

 After drying lor 48 hours in a room, at 70°, their 

 weights were as lollows : — 



101.7 - - - - - • in No. 1. 

 101.5 - - . . in No. 2: 



102 - - - - - in No. 3. 

 No. 1, in drying at- a temperature of about 

 320°, lost 8.8. p. c. of water; after which it was 

 ignited until all organic matter present was dissi- 

 pated : the additional loss thus accruing was 16 

 p. c. The alumina, 'carbonate of lime and sili- 

 cious ingredients were then determined as usual. 

 The result of which inquiry, gave in the hundred 

 parts of earthy matters, as follows: — 



Alumina, with peroxide of iron, - 12 



Carbonate of lime, - - - 10 



Insoluble silica (or fine s^and,) - - 78 



100.0 

 No. 2.— 



Water of absorp'ion, - - 6 p. c. 

 Organic matter, - - - - 8 p. c. 



The proportions among the mineral constitu- 

 ents were as follows : — 



Alumina and Oxide of iron, - 8. 

 Carbonate of lime, -. - - 7.7 

 Insoluble (fine sa-nd,) - - 85.5 



101.2 



7 p. 



- 5 p. 



35 p. 



No. 3.— 



Water of absorption, 

 Organic matter, - - 



Carbonate of lime, - 

 I did not determine the proportions of alumina 

 and silica, presuming that their ingredients have 

 to each other a ratio similar to that found in Nos. 

 1 and 2. 



The iron in this soil is partly in the condition of 

 a carbonate of the protoxide, in place of being a 

 hydraied peroxide, as in Nos. 1 and 2.

NITRATE OF SOBA, 



From tlie London Farmers' Magazine. 



Capt. Alexander has published, at the request 

 of the East Sufl^olk Agricultural Association, the 

 essay on the soils of that district, for which he 

 obtained Mr. Long's prize. It contains much 

 that is valuable, and from it we select the follow- 

 ing extracts, which particularly appertain to some 

 of the soils of this county. 



"The employment of nitrate of potash (salt- 

 petre) and nitrate of soda (cubic-petre) have of
