”First, fetch out your ATLS and log, please.” He glanced toward the darkening sky. “We’ll need to take readings and start our trip chronometers running. Remember, Miss Smythe, it is essential that you start your trip chronometer running very quickly after passing a gate. And shoot an ATLS and star-fix as soon as possible. And as I suspect we’ll have fog soon, do hurry with it. London generally does in the early evenings.”
”But we already know exactly when we are,” Margo pointed out.
”On a tour, yes. As a scout, you won’t. You’ll have to determine that as the opportunity arises. Just because your Timecard was togged in for the Britannia Gate, doesn’t mean you may skip this ritual. Most gates you’ll step through as a scout won’t have an encoder available yet, for the simple reason that you’ll be the first one stepping through it. And when you come through in broad daylight, you’ll have to wait until nightfall to update your exact geo-temporal reading.”
Margo dug out her equipment and took the ATLS reading. Malcolm checked her and made a small correction, then showed her how to take a star-fix. She mastered the knack after three tries and proudly entered the readings in her log.
”There! How did I do?”
”Your ATLS reading was off far enough you’d have placed yourself in the Irish Sea, but not too bad for a first attempt under field conditions. We’ll take readings each night we’re here, to give you the practice.”
Malcolm finished entering data into his own log, made certain Margo had properly initiated the chronometer sequence, then put away their equipment.
