D. FREEMAN.

Los Angeles, Cal., March 7,1884.

[The two bolts and the certificates above referred to accompany the

letter of Mr. Freeman. We can only wonder how it was that, after having

been treated as he relates in the first instance, he should have had any

further business with parties who would send out such boilers, for the

testimony of the engineer and workmen make the case even stronger than

Mr. Freeman has put it.--ED.]
