154 A PRACTICAL TREATISE 



40 to 60 bushels of lime are commonly added. The quantity 

 of this kind of compost commonly applied to an acre, is usually 

 about a ton of the fish and salt, — more or less as the fish pre- 

 vails, and in that country it lias been long considered as a most 

 valuable and lasting manure, though probably its etfects may 

 be at least equally due to the oil and refuse fish, as to the salt 

 with which it is combined. It may also be advantageously 

 mixed with stable-dung alone. 



On meadow ground, Mr. Hollinshead advises the farmer 'to 

 sow six bushels of salt per acre, immediately after the hay is 

 got in; which will not only assist vegetation, and cover the 

 face of the ground with grass, but will induce the cattle to eat 

 up the eddish.' For pasture land, he however recommends 

 the application of foul salt at the rate of 16 bushels per acre ; 

 or, which he seems to prefer, to apply it in the same quantity, 

 mixing with every 16 bushels of the salt 20 loads of earth, 

 turning it two or three tmies, to incorporate it, and laying it 

 on in the autumn. 



In frosty weather, it has excited the surprise of many per- 

 sons that, when the land was quite white through heavy hoar- 

 frost, ground which had been top-dressed with salt remamed 

 perfectly green, and apparently Iree from its effects. It is, 

 indeed, known to chemists to be an enemy to congelation; but 

 we have, as yet, no practical knowledge of its effects, in that 

 view, upon vegetation, nor are we aware that its application 

 would tend to preserve crops from the consequences of frost. 



The quantity of pure salt recommended to be applied to 

 land as manure is from 4 to 16 bushels per acre, beyond 

 which it has been generally found to become injurious to crops 

 when sown with the seed; but, if laid in tlie autumn upon land 

 intended for a clean summer fallow, from 30 to 40 bushels may 

 be spread, according to the condition and nature of the soil. 

 In the directions ibr its use given in the recent treatises of 

 Mr, Cuthbert Johnson, from 5 to 20 bushels are assumed as 

 the limits of its application to different crops; and although 

 we think that, in most cases, the latter quantity would be 

 found too large, and that, in all, the rules for its adoption 

 savour too much of theory, yet as, with due discretion, in 

 many instances tiiey may serve as guides for its employment, 

 we here transcribe tiiem witii very slight alteration : with this 

 observation, that they only apply to the first year's manuring; 

 though it has been stated by Air. Hollinshead and others, that
