Houses in Washington.
--A Washington letter-writer says the demand for places to live in Washington is treble the supply already, and when Congress meets it will be as difficult to accommodate all the people as it used to be on inauguration days. Such a thing as a vacant house is unheard of. Ordinary houses on the back streets, that once rented for $150 and $200 per annum, are now commanding double that amount, and the tenant often gives a premium of $100 or so for the privilege of paying such a rent. It is estimated that from five hundred to a thousand vacant houses are needed at this moment. Only the rich can keep houses.
