With Reeder and Longaker to Morristown on train—then a long tramp west to Valley Forge and back—taking 9:05 train again from Philadelphia. Reeder showed me proofs of yesterday's experiments—the close view (dark as it was) quite satisfactory—the other not so fortunate. It had proved too near night to make a picture of W.—therefore the parlor experiment also failed. The walk perfect, under a cloudless sky and with noble companions: all I could have wished. Cherries common—leaned over road as if everywhere inviting welcome and giving it. We talked a good deal about W.'s condition, Longaker convinced that it had now phases of considerable hope. Johnston's facsimile letter everywhere admired: J. sent one to Longaker, one to Warren—no doubt since a few others. Met Buckwalter, still moved by the dinner—will give me a brief abstract of his dinner remarks. Not in Camden till after eleven. Tom in to see W. today—I, of course, had no chance, having spent Saturday night at the Lychenheims'.
