meant anything, there was, with Zitta's observation,--
whoever Zitta might be,--something to start upon. We
rushed upon some old bound volumes of the Record and
spotted the "enlightened Gmelin." He was chief of a
college at Taganrog, where perhaps they had a spyglass.
This gave us the parallax of his observation. Breslau,
of course, we knew, and so we could place Zitta's,
and with these poor data I went to work to construct,
if I could, an orbit for this Io-Phoebe mass of brick and
mortar. Haliburton, not strong in spherical
trigonometry, looked out logarithms for me till
breakfast, and, as soon as it would do, went over to Mrs.
Bowdoin, to borrow her telescope, ours being left at No.
9.

Mrs. Bowdoin was kind, as she always was, and at noon
Haliburton appeared in triumph with the boxes on P.
Nolan's job-wagon. We always employ P., in memory of
dear old Phil. We got the telescope rigged, and waited
for night, only, alas! to be disappointed again. Io had
wandered somewhere else, and, with all our sweeping back
and forth on the tentative curve I had laid out, Io would
not appear. We spent that night in vain.

But we were not going to give it up so. Phoebe might
have gone round the world twice before she became Io;
might have gone three times, four, five, six,--nay, six
hundred,--who knew? Nay, who knew how far off Phoebe-
Io was or Io-Phoebe? We sent over for Annie, and
she and Polly and George and I went to work again. We
