There is a letter published in 1848 describing the improved performance of the water turbine or scotch mill erected in 1843

Ballaughton Mills,
Isle of Man,
10th April, 1843.
Mr. James WHITELAW.

Dear Sir,—Having one of your patent water-mills, and feeling particularly well pleased with its working, I have been testing its power, by drawing a comparison between our mill and Pulrose Mill, situated about 400 yards below us, on the same stream of water. The following results will convince every person who understands the subject, that your patent water-mill will work to very great advantage on a low fall, compared with the common water-wheel, and any person desirous to see both mills at work can satisfy himself at any time by calling on me :—

Our fall of water is 8 feet 6 inches, and the water-mill is 9 feet 6 inches diameter — it has 4 arms, and works in tail-water. When the 4 arms are open we drive 6 pairs of stones, each 4 feet 8 inches diameter, viz.: 2 pairs grinding wheat, 2 pairs barley, 1 pair making oatmeal and sifting at same time, and 1 pair shelling oats with the scree and fanners. With 3 arms open — 2 pairs wheat, 1 pair barley, and 1 pair oatmeal, as before. With 2 arms open—2 pairs wheat, and 1 flour cylinder. With 1 arm open — 1 pair wheat, and 1 flour cylinder. Our flour cylinders are 18 inches diameter and 7 feet long. The quantity of wheat we grind per hour on each pair of stones is 6 bushels, and of barley 4 bushels, and oatmeal 10 cwt.; on each cylinder 16 cwt. of fine flour. It may be as well to observe, that all our barley is kiln-dried before grinding, and is ground into a very fine flour for making bread ; consequently it is much harder and takes more power than wheat. The speed of the water-mill, when working as above, is exactly 54 revolutions per minute, our stones 108 revolutions, and our flour cylinders 470 revolutions per minute.

Pulrose Mill has a fall of 7 feet, and is worked by an undershot water-wheel 15 feet diameter and 5 feet wide. It is only 4 years old, and is made upon the very best principle, and there is no loss of water between the two mills. When our 4 arms are open, at Pulrose Mill they have more water than they can consume. Our 3 arms give the exact quantity required by them to drive 1 pair of wheat-stones, 4 feet 6 inches diameter, grinding 5 bushels wheat per hour ; and 1 pair barley, grinding 3 bushels per hour. When our 2 arms are open they have barely enough of water to work 1 pair of wheat- stones, and 1 flour cylinder (16 inches diameter by 5 feet long) dressing 8 cwt. fine flour per hour. When 1 of our arms is open, they are scarcely able to grind 3 bushels of wheat per hour, without any other part of the machinery at work. You are at liberty to make what use you think proper of this letter, and to refer any person for farther information respecting our mill to, dear sir yours very respectfully. Robt Donaldson

Robert Donaldson can be found in the 1841 census as as 25year old Miller & Corn factor living at Millmount Braddan
