[D8835ABB], Letter from John Kruesi to Charles Batchelor, February 9th, 1888

Editor's Notes

"In answer to your favor of the 8th inst., with relation to the inside iron case of the Tuyere, we would say that we have come to the same conclusion, and have given instructions to have a casting made in exactly the way that your sketch shows. ### Upon inquiry made yesterday, I found that in one foundry they had to make twelve castings before one good one could be obtained, and in our foundry they have made eight castings and have not as yet succeeded in getting out a good one. I am extremely sorry that my attention was not callled to this sooner. It is a casting which it is next to an impossibility to make, as there is a very thin and long core within another core without any means of carrying off the gases, and consequently owing to his difficulty it is a mere matter of good luck to get out a good casting. A wrought iron pipe will answer the purpose just as well, and will cause you no trouble. We will, however, finish the one we have now under way in order to have one in stock in case either you, or oursevles should want one." Very truly yours, John Kruesi
