I am writing to Mr. Butler, the Mineralogist, to settle with him about this last instalment completing the series of specimens. He is not a mere seller of stones. I think I may tell him that you are satisfied with his collection - that you have already done good work & gone at it in the true Educational spirit - & taught the boys to collect specimens themselves & in your Science classes are going to give one on Geology, & two Lectures on Coal etc at an Institute. - thus training the men & boys
