【正文】 with painful selfconsciousness and the flattened nose and was married by the first girl who was nice to him He was married five years had three children lost most of the fifty thousand dollars his father left him the balance of the estate having gone to his mother hardened into a rather unattractive mould under domestic unhappiness with a rich wife and just when he had made up his mind to leave his wife she left him and went off with a miniaturepainter As he had been thinking for months about leaving his wife and had not done it because it would be too cruel to deprive her of himself her departure was a very healthful shock The divorce was arranged and Robert Cohn went out to the Coast In California he fell among literary people and as he still had a little of the fifty thousand left in a short time he was backing a review of the Arts The review menced publication in Carmel California and finished in Provincetown Massachusetts By that time Cohn who had been regarded purely as an angel and whose name had appeared on the editorial page merely as a member of the advisory board had bee the sole editor It was his money and he discovered he liked the authority of editing He was sorry when the magazine became too expensive and he had to give it up By that time though he had other things to worry about He had be She turned to face the camera Send me what you can about hydrogen ramscoop engines she said See if you can give me some idea of what to look for if Themis has one Youll have to take your shirt off Calvin said Cirocco reached up and switched off the camera leaving the sound on Calvin thumped her back and listened to the results while Cirocco and Gaby continued to study the picture of Themis They came up with no new insights until Gaby brought UP the matter of the cables As far as 1 can tell they form a circle about midway between the hub and the rim They support the top edges of the reflecting panels sort of like the rigging on a sailing ship What about these Cirocco asked indicating the area between two of the spokes Any idea what theyre for Nope Theres six of them and they run midway between the spokes from the hub to the rim radially They pass through th frared which seems to be the best spectrum Cirocco raised herself on one elbow careful not to dislodge any of Calvins electrodes She chewed on the end of the thermometer until he frowned at her The print showed a fat wagon wheel surrounded by broad based bright red triangular areas There were six red areas on the inside of the wheel but they were smaller and square The big triangles on the outside are the hottest parts Gaby said I figure theyre part of the temperature control system They soak up heat from the sun or bleed off the excess Houston already decided that Cirocco pointed out She glanced at the television camera near the ceiling Ground control was monitoring them If they thought of something Cirocco would hear of it in a few hours asleep or not The wheel analogy was almost literally true except for the heating or cooling fins Gaby had indicated There was a hub in the center and it had a hole which could have taken an axle if Themis had actually been a wagon wheel Radiating from the hub were six thick spokes which flared gradually just before joining the outer portion of the wheel Between each pair of spokes was one of the bright square areas This is whats new Gaby said Those squares are angled Theyre what 1 originally saw the six points of light Theyre flat or theyd scatter a lot more light As it is they only reflect light to Earth if theyre at just the right angle and thats rare What kind of angle Cirocco lisped Calvin took the thermometer out of her mouth Okay Light es in parallel to the axis from this angle She moved an extended finger toward the print The mirrors are set to deflect the light niy degrees into the wheel roof She touched the paper with her finger turned the finger and indicated an area between two spokes This part of the wheel is hotter than the rest but not so hot that it could be soaking up all the heat it gets Its not reflecting it or absorbing it so its transmitting it Its transparent or trans lucent it lets most of the light go through to whatevers underneath Does that suggest anything to you Cirocco looked up from her careful examination What do you mean Okay We know the wheel is hollow Maybe the spokes are too Anyway picture the wheel Its like a car tire big and fat and flat on the bottom to give more living space Centrifugal force pushes you away from the hub Ive got all that Cirocco said slightly amused Gaby could he so intense when explaining something Right So when youre standing on the inside of the wheel youre either under a spoke or under a reflector right Yeah Oh yeah So So its always either daytime or nighttime at any particular spot The spokes are rigidly attached the reflectors dont move and neither can the skylights So it has to be that way Permanent day or permanent night Why do you think theyd build it that way To answer that wed need to meet them Their needs must he different from ours She looked back at the picture She had to keep reminding herself of the size of the thing Thirteen hundred meters in diameter 4000 around the outer rim The prospect of meeting the beings who built such a thing was worrying her more each day All right 1 can wait Gaby was not that interested in Them is as a spacecraft To her it was a fascinating problem in observation en there Id like to know I am more like Earth than Earth now is Nicholas If you were to take
