Our readers will remember that we mentioned on page 285, of having received a letter from a correspondent in Oldham, Lancashire, Eng., stating that the use of soda for the prevention of incrustations in steam boilers was deleterious, inasmuch as " a brother of his ruined a good steam boiler in a short time by its use." A letter from C. W. Cooke, of Waterloo, ?. Y., informs us that he has used soda to prevent incrustations in steam boilers for two years, and has found it to be a perfect re. medy. Our English correspondent must inform himself more perfectly on the subject, as there is a great amount of testimony against his conclusions. The Legislature and some of the press went on a grand excursion on the consolidated line from Albany to Niagara on Saturday . last week.
