POWELL’S DUFFRYN COAL-Testimonials.

South-Western Steam Packet Company, Southampton, August 31si, 1844.

I hereby certify that, having sole management of the Steam Vessels belonging to this Company, andhaving tried several descriptions of Welsh Coal on the common and tubular boilers, none have been foundequal to Powell’s Duffryn Steam Coal, the saving of fuel being in both descriptions of boilers about one-fifthover that of any others that have been tried ; that for tubular boilers I have frequently stated to otherCoal proprietors, I have not found any equal to them in keeping the tubes and flues clean. I may furtherstate that, in the consumption of about 5000 tons, I have found little or no variation in the quality of theseveral cargoes. (Signed) N. M. PEIAULX, General Manager.

I hereby certify, that Powell’s Duffryn Steam Coal was tried in three vessels belonging to the Penin-sular and Oriental Steam Company, namely, the “Royal Tar,Lady Mary Wood,” and “ Great Liverpool,”and the reports from all these vessels were highly favourable as to its efficiency and economical combustion.Given under my hand at Southampton, this 17th day of March, 1843.

E. S. KENDALL, Superintendent.

Having used Powell’s Duffryn Steam Coal for the last seven months in the Steam Ship “ Osprey,”trading between Bristol and Waterford, we find a saving of at least from eight to ten tons per voyage inour consumption, over the Coal we formerly burnt.

The same fire-bars are now in use that have been from the commencement of our having the DuffrynSteam Coal, and are no more injured than they would have been had we used any other Coal.

Having used Powell’s Duffryn Steam Coal on board the Steamer “ Shamrock,” I find that it possessesgreat power in generating Steam, its durability is at least one-third greater than Scotch Coal, it makes butfew ashes, and does not clinker nor burn the bars.

I have used in our Steamers Powell’s Duffryn Steam Coal, and I find it to be at least one-third moredurable than Scotch Coal, of greater strength, and quite free from clinker.

Liverpool, 15 th October, 1850.

Having used Towell’s Duffryn Steam Coal in the United States Mail Ship “ Pacific,” plying betweenLiverpool and New York, I have much pleasure in certifying that it is decidedly the best Steam Coal I haveyet known, both from its durability and power of generating Steam. The “Pacific” having performedthe last voyage from Liverpool to New York in ten days and four-and-a-half hours, being the shortest onrecord ; which I partly attribute to the very superior quality of the Coal.

Liverpool, October 15 th, 1850.

This may certify that I have been using Powell’s Duffryn Steam Coal for the past six months on boardthe U. S. Mail Steamer “Atlantic,” plying between this Port and Now York, and without hesitation mustsay, on all occasions, have found the quality most excellent, and believe it to be equal, if not superior, toany Coal now used.
