"Almost," acknowledged Isobar gloomily. "It prob'ly ain't right, though. How anybody can be expected to get anything right on this dagnabbed hunk o' green cheese—"

"Send it up," interrupted Colonel Eagan, "as soon as you can. Sparks is making Terra contact now. That is all."

"That ain't all!" declared Isobar indignantly. "How about my bag—?"

It was all, so far as the D.C. was concerned. Isobar was talking to himself. The plate dulled. Isobar said, "Nuts!" and returned to his duties. He jotted neat ditto marks under the word "Clear" which, six months ago, he had placed beneath the column headed: Cond. of Obs. He noted the proper figures under the headings Sun Spots: Max Freq.Min. Freq.; then he sketched careful curves in blue and red ink upon the Mercator projection of Earth which was his daily work sheet.

"I—er—I beg your pardon, Isobar?" queried a mild voice.

Isobar started. His sallow cheeks achieved a sickly salmon hue. He blinked nervously.
