BY HIS PATENTS COMPARED WITH OTHERS. 215 



From the preceding statement it is evident that Mr. 

 Marshall reduced 12cwt. of green straw into 9cwt. when 

 retted, and produced only 1 cwt. 5lbs. of fibre. As other 

 experiments appeared in the Flax Society's reports, the result 

 of each, must be interesting to Flax-growers. Schenk's 

 patent hot water and the old cold water system has been 

 reported to produce from Iflbs. to 2 Jibs of fibre out of 14lbs. 

 of retted straw, the following has been calculated accordingly 

 in order to prove the production from the several modes of 

 preparing Flax for market. 



By Mr. Marshall's hot water experiment, lOcwt. Iqr. 25lbs. 

 would not produce more than 1 02lbs. of fibre. 



By Mr. Andrews' hot water experiment, lOcwt. Iqr. 25lbs. 

 would not produce more than 115lbs. of fibre. 



By Mr. W. Adam's hot water experiment, lOcwt. Iqr. 25lbs. 

 would not produce more than 126lbs. of fibre. 



By Mr. Warne's cold water experiment, lOcwt. Iqr. 25lbs. 

 would not produce more than 122lbs. of fibre. 



By Mr. Dickson's patent machines and patent liquid, 

 lOcwt. Iqr. 25lbs. produce 336lbs. green Flax and 84lbs. of 

 tow ; total, 42 Gibs. Deduct 25 per cent, as waste in boiling 

 in the liquid, 104lbs., leaving 31 Gibs, of perfectly white fibre. 

 It thus appears that Mr. Arthur Marshall, at Patrington, 

 produced out of 12cwt. 3lbs. of green straw, Icwt. 5lbs. of 

 scutched, and 64lbs. of hackled Flax ; and at Belfast, out of 

 12cwt. 51bs. of green straw, Icwt. 8lbs. scutched, and 62lbs. 

 of hackled Flax. Dickson's patents at Deptford produced, 

 from 12cwt. of green straw, 4cwt. Iqr. 4lbs. of scutched, and 

 245lbs. of hackled Flax. 



Looking at the above experiments, which I quote as an 

 example of what others have produced from a given quantity, 

 I am prepared to prove the working of my patent machines 

 and liquid as follows ;
