FISH. 



It is evident, from the experience of all who 

 have tried blubber, that it is best used when 

 previously mixed with from 10 to 20 times i 

 weight of earth, and turned over once or twic 

 during three or four months. In its uncombine 

 state it is evidently too powerful. When mixe 

 with mould, it speedily undergoes a strong fe 

 mentation, and the mass becomes of the mos 

 friable and fertilizing description. Train o 

 has also been employed with the most decide 

 success ; it has been used united with screene 

 earth, and produced the most luxuriant o 

 crops. In an experiment made by Mr. Mason 

 of Chilton, which is described by Lord Spen 

 cer, in a communication furnished to the Don 

 caster Agricultural Society, 40 gallons of un 

 refined train oil, which cost 8$d. per gallon 

 were mixed with 120 bushels of screened eartl 

 about a month before it was applied to one acre 

 of a tenacious soil, sown with turnips ; and on 

 an adjoining acre of similar land were appliec 

 40 bushels of bones, broken small, and mixec 

 with 80 bushels of burnt earth ; the crop pro 

 duced was as follows :

And in The Mark Lane Express of February 8 

 1841, Mr. W. Sharp, of Scarthing Moor, in Not 

 tinghamshire, thus describes his experiment 

 with fish oil, mixed with bone dust: "I will 

 give you my experiment with oil. The soil is 

 a poor gravel, the farm in the parish of Ed- 

 winstow, and enclosed off the old Forest, near 

 to Thorseby Park. 



"My attention was drawn to the use of oil in 

 consequence of the serious expense (3/. to 41. 

 per acre) I was obliged to go to in bones and 

 rape dust, for I never use yard manure for tur- 

 nips, as the soil is so poor, I cannot get wheat 

 without manure ; I therefore save it all for my 

 wheat. My first trial was in 1839, on 2 acres, 

 in a 9-acre field, and nearly in the middle of it.

"The oil turnips were as good as the re- 

 mainder of the field ; and all as fine as I could 

 wish, for the land. The barley as good, and 

 the clover is now excellent. My next trial in 

 1840, on 9 acres,

"I think the 9 acres with oil rather the best 

 field, and the turnips are decidedly better. The 

 rape-dust I sow broadcast on the surface ; it is 

 then drawn in its proper place by ridging; I 

 then drill my bones on the ridges 22 inches 

 apart, the turnips were white tops. I do not 

 like the ashes mixed with the oil ; it makes it 

 dirty and bad to drill ; the 1 1 strikes of bones 

 carefully mixed will absorb the oil, so as to 

 drill excellent. I let them lie about two days 

 after mixing. I know your readers will say, 

 how is barley grown after so light a dressing! 

 I answer with my feeding sheep I use oil- 

 cake, and with my store sheep malt-coombs, 

 and the straw in the yard is all consumed _ 

 with oil-cake I take my seeds up for wheat. 



"Some farmers may possibly doubt the cor- 

 rectness of my assertion, that all the principal 

 vegetable substances are composed of precise- 

 y the same ingredients as oil and other purely 

 animal matters ; and as it is of the first im- 

 portance that the cultivator should clearly un- 

 derstand the reason why the decomposition of 

 animal matters furnishes such admirable food 

 "or vegetation, I must beg of him to compare 

 he analysis of the oils which I have already 

 stated, with that of the following common vege- 

 able substances, as ascertained by the most 

 careful analysis. I will merely give that of 

 hree substances : sugar, 100 parts of which 

 are composed, according to M. Berzelius, of

"All oily and other animal substances, there- 

 I fore, as they decompose in the soil, are slowly 



converted into those gaseous substances which 

 . are the food or breath of vegetable life, such as 

 ; carbonic acid gas (fixed air) or carburetted 

 i hydrogen (the gas employed for illumination), 



and which are absorbed either by the roots or 



the leaves of the plant as they are formed. 



There is little or no waste in these, for when
