Dear sisters:--The carriage was full to overflowment; E. E. and I filled it with the sumptuosity of our garments. Dempster was nowhere. Now and then the carriage jolted his head into sight--that was all. Mrs. Sprague lives in a great, square corner-house that looks rich and respectable--two things that do not always come together in these days, when people creep into society, and build themselves up there on the property that should belong to the Government. It has some wide, jutting windows, and plenty of room inside. The hall-way was crowded full of ladies, and so was the stairs. Some were going up, and some were coming down. The first in shawls and cloaks, the others with their arms and necks uncovered, or with just a shadow of lace on them, nothing more. The great square chamber that we went into was as full as a bee-hive. Silks swept and rustled against each other like oak-leaves when the wind shakes them. The great looking-glasses were full also--you saw a crowd of handsome faces coming and going in them all the time. Each glass was like a picture always changing. The bed was covered over with cloaks and shawls, but you could see that the bedstead was beautifully carved, and the pillow-cases were ruffled all round and edged with lace. On a table near the door was a case of shiny black wood, curlicued with gold, and lined with velvet. In it was a lot of gold things, essence bottles, knives, scissors with gold handles, and glass cases with gold lids. It lay open, and anybody could use the things that wanted to; I didn't, but had a good look while E. E. was titivating in the crowd before the glass. My dress must have carried out the grand idea in my mind when I made it, for all the ladies stopped, and gave me a good, long look before they went out, and I could see smiles of approbation dancing about their mouths. My triumph commenced, sisters, even in the dressing-room. Dempster was waiting for us, and we followed him downstairs into the largest and handsomest room I've seen in Washington City. It was just afire with lights. The great curving window was crowded full of flowers; every table in the room blazed out with them. Two folding-doors, like those we have in a Vermont meeting-house, opened into another great room, just as rainbowish with light, and smelling just as sweet with flowers--I never saw anything like it. A crowd went in with us, and we had to wait till they let us go up to Judge Chase and Mrs. Sprague, who stood in the front room.
