I am on the point of seeing something important when the speaker announces in the colonel's voice that Professor M'Clare and Miss Lee will report to the Conference Room at once please.

M'Clare looks at me and grins. "Come along, Lizzie. Here's where we take orders for once, you and I."

It is the colonel's Hour. I suppose that having to work with Undergraduates is something he could never quite forget, but from the way he looks at us we might almost be Space Force personnel,—low-grade of course but respectable.

Everything is at last worked out and he has it on paper in front of him; he puts the paper four square on the table, gazes into the middle distance and proceeds to recite.

"One. This ship will go off Mass-Time on 2nd August at 11.27 hours ship's time....

"Thirty-six hours from now.

"... At a point one thousand miles vertically above Co-ordinates 165OE, 7320S, on Planet Incognita, approximately one hour before midnight local time.

"Going on planetary drive as close as that will indicate that something is badly wrong to begin with.

"Two. This ship will descend, coupled to Gilgamesh as at present, to a point seventy miles above the planetary surface. It will then uncouple, discharge one hopper, and go back on Mass-Time. Estimated time for this stage of descent forty minutes.

"Three. The hopper will then descend on its own engines at the maximum speed allowed by the heat-disposal system; estimated at thirty-seven minutes. Gilgamesh will complete descent in thirty-three minutes. Engines of Gilgamesh will not be used except for the heat-disposal and gyro auxiliaries. The following installations have been made to allow for the control of the descent; a ring of eight rockets in peltathene mounts around the tail and, and one outsize antigrav unit inside the nose. "Sympathizer" controls hooked up with a visiscreen and a computer have also been installed in the nose.
