I had three letters of enquiry to answer today, two of which required a careful examination of the laws and of the Treaty stipulations with Great Britain. They consumed much of my morning. At about four I went out with Mrs Adams in the carriage, and we paid a visit to Mr and Mrs Twisleton. He is one of the most reasonable and pleasant men I have met in England. From thence we drove round to see the building in process of erection for the great Exhibition of next year. It is scarcely yet erected even in the outline, but the extent of it is prodigious. The expenditure is doubtless paid for by the increased facilities it is the means of procuring for trade and manufactures. Yet the magnitude of these undertakings is among the peculiar characteristics of modern times. I read today an article in the Edinburgh Review upon the American question. Pretty much on a par with every thing else written here excepting that the tone is more candid. Why is that the philosophy of government is so imperfectly studied here? I do not know of a single profound writer on it. Evening spent quietly at home. Continued Whitelock.258
