The exclusion of wine from the list of refreshments has turned out exceedingly well. There is a great deal of dissipation here [in Washington DC] At the reception of the British Minister, and that of the Mexican Minister, disgraceful things were done by young men, made reckless by too much wine. Hence the necessity of our course is obvious, and is commended in unexpected quarters. Many of the foreign gentlemen speak of it with approval. We shall stick to it.
