famous builders of the past.  He visited the workshops of Hill, Gray and Davidson, Willis, Robson, and others.  He made a visit to Oxford to examine the beautiful organ in Trinity College.  He found his way into the organ-lofts of St. Paul’s, of Westminster Abbey, and the Temple Church, during the playing at morning and evening service.  He inspected Thompson’s enharmonic organ, and obtained models of various portions of organ-structure.

From London Dr. Upham went to Holland, where he visited the famous instruments at Haarlem, Amsterdam, and Rotterdam, and the organ-factory at Utrecht, the largest and best in Holland.  Thence to Cologne, where, as well as at Utrecht, he obtained plans and schemes of instruments; to Hamburg, where are fine old organs, some of them built two or three centuries ago; to Lubeck, Dresden, Breslau, Leipsic, Halle, Merseburg.  Here he found a splendid organ, built by Ladergast, whose instruments excel especially in their tone-effects.  A letter from Liszt, the renowned pianist, recommended this builder particularly to Dr. Upham’s choice.  At Frankfort and at Stuttgart he found two magnificent instruments, built by Walcker of Ludwigsburg, to which place he repaired in order to examine his factories carefully, for the second time.  Thence the musical tourist proceeded to Ulm, where is the sumptuous organ, the work of the same builder, ranking, we believe, first in point of dimensions of all in the world.  Onward still, to Munich, Bamberg, Augsburg, Nuremberg, along the Lake of Constance to Weingarten, where is that great organ claiming to have sixty-six stops and six thousand six hundred and sixty-six pipes; to Freyburg, in Switzerland, where is another great organ, noted for the rare beauty of its vox-humana stop, the mechanism of which had been specially studied by Mr. Walcker, who explained it to Dr. Upham.

Returning to Ludwigsburg, Dr. Upham received another specification from Mr. Walcker.  He then passed some time at Frankfort examining the specifications already received and the additional ones which came to him while there.

At last, by the process of exclusion, the choice was narrowed down to three names, Schultze, Ladergast, and Walcker, then to the two last.  There was still a difficulty in deciding between these.  Dr. Upham called in Mr. Walcker’s partner and son, who explained every point on which he questioned them with the utmost minuteness.  Still undecided, he revisited Merseburg and Weissenfels, to give Ladergast’s instruments another trial.  The result was that he asked Mr. Walcker for a third specification, with certain additions and alterations which he named.  This he received, and finally decided in his favor,—­but with the condition that Mr. Walcker should meet him in Paris for the purpose of examining the French organs with reference to any excellences of which he might avail himself, and afterwards proceed to London and inspect the English instruments with the same object.
