Their father, a brewer by trade but a naturalist by avocation, had educated Christopher and Sarah Anne together after their mother’s death, as if they were brothers. The three of them rambled the grounds of Burdem Place, learning the names of the plants and birds. Collinson lived in Peckham then, just a few miles away, and he often rode over bearing rare plants and seeds sent by naturalist friends in other countries. Peter Kalm, Linnaeus’s famous student, visited the Billopps; Linnaeus himself, before Sarah Anne was born, once stayed for several days.
All these things are part of Sarah Anne’s and Christopher’s common past. And even after Christopher’s return from Cambridge and their father’s death, for a while they continued to enjoy an easy exchange of books and conversation. But now all that has changed. Sarah Anne inherited her father’s brains but Christopher inherited everything else, including his father’s friends. Sarah Anne acts as hostess to these men, at Christopher’s bidding. In part she’s happy for their company, which represents her only intellectual companionship. In part she despises them for their lumbago and thinning hair, their greediness in the presence of good food, the stories they repeat about the scientific triumphs of their youth, and the fact that they refuse to take her seriously. Not one of them has done anything original in years.
There’s another reason, as well, why she holds her tongue on this night. Lately, since Christopher has started courting Miss Juliet Colden, he’s become critical of Sarah Anne’s manners. She does not dress as elegantly as Juliet, or comport herself with such decorum. She’s forward when she ought to be retiring, he has said, and disputatious when she should be agreeable. He’s spoken to her several times already: “You should wear your learning modestly,” he lectures.
She does wear it modestly, or so she believes. She’s careful not to betray in public those subjects she knows more thoroughly than Christopher. Always she reminds herself that her learning is only book-learning; that it hasn’t been tempered, as Christopher’s has, by long discussions after dinner and passionate arguments in coffeehouses with wiser minds.
And so here she is: learned, but not really; and not pretty, and no longer young: last month she turned twenty-nine. Old, old, old. Like her company. She knows that Christopher has begun to worry that she’ll be on his hands for life. And she thinks that perhaps he’s mentioned this worry to his friends.
They’re fond of him, and of Burdem Place. They appreciate the library, the herbarium, the rare trees and shrubs outside, the collections in the specimen cabinets. They appreciate Sarah Anne as well, she knows. Earlier, they complimented the food, her gown, the flowers on the table and her eyes in the candlelight. But what’s the use of that sort of admiration? Collinson, who has known her the longest, was the only one to make a stab at treating her the way they all had when she was a girl: he led her into quoting Pliny and then complimented her on her learning. But she saw the way the other men shifted uneasily as she spoke.
Despite herself, she continues to listen to the men’s conversation. Despite her restlessness, her longing to be outside in the cool damp air, or in some other place entirely, she listens because the subject they’re discussing fascinates her.
“I had a letter last year from Solander,” Ellis says. “Regarding the November meeting of the Royal Society. There, a Reverend Forster said he’d observed large flocks of swallows flying quite high in the autumn, then coming down to sit on reeds and willows before plunging into the water of one of his ponds.”
“More hearsay,” Collinson says.
But Pennant says it might be so; either that or they slept for the winter in their summer nesting holes. “Locke says that there are no chasms or gaps in the great chain of being,” he reminds them. “Rather there is a continuous series in which each step differs very little from the next. There are fishes that have wings, and birds that inhabit the water, whose blood is as cold as that of fishes. Why should not the swallow be one of those animals so near of kin to both birds and fish that it occupies a place between both? As there are mermaids or seamen, perhaps.”
No one objects to the introduction of aquatic anthropoids into the conversation. Reports of them surface every few years—Cingalese fishermen swear they’ve caught them in their nets, a ship’s captain spots two off the coast of Massachusetts. In Paris, only four years ago, a living female of the species was exhibited.
Collinson says, “Our friend Mr. Achard writes me that he has seen them hibernating in the cliffs along the Rhine. But I have my doubts about the whole story.”
“Yes?” Pennant says. “So what do you believe?”
“I think swallows migrate,” Collinson says.
While the servants change plates, replace glasses, and open fresh bottles of wine, Collinson relates a story from Mr. Adanson’s recent History of Senegal. Off the coast of that land in autumn, he says, Adanson reported seeing swallows settling on the decks and rigging of passing ships like bees. Others have reported spring and autumn sightings of swallows in Andalusia and over the Strait of Gibraltar. “Clearly,” Collinson says, “they must be birds of passage.”
Which is what Sarah Anne believes. She opens her mouth and proposes a simple experiment to the men. “The swallow must breathe during winter,” she says, between the soup and the roasted veal. “Respiration and circulation must somehow continue, in some degree. And how is that possible if the birds are under water for so long? Could one not settle this by catching some swallows at the time of their autumn disappearance and confining them under water in a tub for a time? If they are taken out alive, then Linnaeus’s theory is proved. But if not…”
“A reasonable test,” Collinson says. “How would you catch the birds?”
“At night,” she tells him impatiently. Oh, he is so old; he has dribbled more gravy on his waistcoat. How is that he can no longer imagine leaving his world of books and talk for the world outside? Anyone might gather a handful of birds. “With nets, while they roost in the reeds.”
Collinson says, “If they survived, we might dissect one and look for whatever internal structure made possible their underwater sojourn.”
He seems to be waiting for Sarah Anne’s response, but Christopher is glaring at her. She knows what he’s thinking: in his new, middle-aged stodginess, assumed unnecessarily early and worn like a borrowed coat, he judges her harshly. She’s been forward in entering the conversation, unladylike in offering an opinion that contradicts some of her guests, indelicate in suggesting that she might pursue a flock of birds with a net.
What has gotten into him? That pulse she hears inside her ear, the steady swish and hum of her blood, is the sound of time passing. Each minute whirling past her before she can wring any life from it; hours shattered and lost while she defers to her brother’s sense of propriety.
Upstairs, finally. Dismissed while the men, in the library below, drink Christopher’s excellent wine and avail themselves of the chamberpot in the sideboard. Her brother’s friends are grateful for her hospitality, appreciative of her well-run household; but most grateful and appreciative when she disappears.
Her room is dark, the night is cool, the breeze flows through her windows. She sits in her high-ceilinged room, at the fragile desk in the three-windowed bay facing west, over the garden. If it were not dark, she could see the acres leading down to the lake and the low stretch of rushes and willows along the banks.
Her desk is very small, meant to hold a few letters and a vase of flowers: useless for any real work. The books she’s taken from the library spill from it to the floor. Gorgeous books, expensive books. Her brother’s books. But her brother doesn’t use them the way she does. She’s been rooting around in them and composing a letter to Linnaeus, in Uppsala, about the evening’s dinner conversation. Christopher need never know what she writes alone in this room.
