Mama BekwaTataba stood watching us-a little jet-black woman. Her elbows stuck out like wings, and a huge white enameled tub occupied the space above her head, somewhat miraculously holding steady while her head moved in quick jerks to the right and left. Mama Tataba’s job, we were surprised to learn, was to live with us and earn a small stipend by doing the same work she’d done for our forerunner in the Kilanga Mission, Brother Fowles. He’d left us two boarders, in fact: Mama Tataba and a parrot named Methuselah. Both had been trained by him in the English language and evidently a good deal else, for Brother Fowles left some mystery in his wake. I gathered through overhearing my parents that Brother Fowles had entered into unconventional alliances with the local people, and too he was a Yankee. I heard them saying he was New York Irish, which tells you a lot, as they are notorious for being papist Catholics. Father explained to us that he had gone plumb crazy, consorting with the inhabitants of the land.

That’s why the Mission League finally allowed us to come. At first they’d insulted my father by turning us down, even after our Bethlehem congregation had done special tithes for a whole year to fly us here for the perfusion of Jesus’ name. But no one else volunteered for the Kilanga post, and the Underdowns had requested that it be taken by someone steady, with a family. Well, we were a family all right, and my father is steady as a stump. Still, the Underdowns insisted that our mission last no more than one year-not enough time for going plumb crazy but only partway, I guess, even if things went poorly.

Brother Fowles had been in Kilanga six years, which really when you think about it is long enough for about any kind of backsliding you could name. There was no telling how he might have influenced Mama Tataba. But we needed her help. She carried all our water up from the river and cleaned and lit the kerosene lamps and split wood and built the fire in the cookstove and threw buckets of ash down the hole in the outhouse and paused to kill snakes more or less as a distraction between heavier jobs. My sisters and I stood in awe of Mama Tataba, but were not quite used to her yet. She had a blind eye. It looked like an egg whose yolk had been broken and stirred just once. As she stood there by our garden, I stared at her bad eye, while her good eye stared at my father.

“What you be dig for? Worm grub?” she demanded. She turned her head slightly from side to side, surveying my father’s work with what he calls her “acute monocular beam.” The galvanized bucket remained perfectly still on top of her head-a great, levitating crown.

“We’re cultivating the soil, sister,” he said.

“That one, brother, he bite,” she said, pointing her knuckly hand at a small tree he was wresting from his garden plot. White sap oozed from the torn bark. My father wiped his hands on his trousers.

“Poisonwood,” she added flatly, emphasizing the descending syllables as if she were equally tired of all three.

My father mopped his brow again and launched into the parable of the one mustard seed falling on a barren place, and the other one on good soil. I thought of the bright pointy-nosed mustard bottles we used in abundance at church wiener suppers-a world apart from anything MamaTataba had ever seen. Father had the job of his life cut out for him, bringing the Word to a place like this. I wanted to throw my arms around his weary neck and pat down his rumpled hair.

Mama Tataba seemed not to be listening. She pointed again at the red dirt. “You got to be make hills.”

He stood his ground, my father, tall as Goliath and pure of heart as David. A film of red dust on his hair and eyebrows and the tip of his strong chin gave him a fiendish look untrue to his nature. He ran his large, freckled hand across the side of his head, where his hair was shaved close, and then through the tousled crown, where Mother lets it grow longer. All this while inspecting Mama Tataba -with Christian tolerance, taking his time to formulate the message.

“Mama Tataba,” he said at last, “I’ve been tending the soil ever since I could walk behind my father.”

When he says anything at all, even a simple thing about a car or a plumbing repair, it tends to come out like this-in terms that can be interpreted as sacred.

Mama Tataba kicked the dirt with her flat, naked sole and looked disgusted. “He won’t be grow. You got to be make hills,” she stated, then turned on her heel and went in the house to help my mother slosh Clorox water across the floor to kill the hookworms.

I was shocked. In Georgia I’d seen people angered by my father before, or intimidated, but not contemptuous. Never.

“What does she mean, make hills?” I asked. “And why did she think a plant could bite you?”

He showed no trace of concern, though his hair blazed as if it had caught fire in the late-afternoon light. “Leah, our world is filled with mystery” was his confident reply.

Among all of Africa’s mysteries, here were the few that revealed themselves in no time flat. My father woke up the next morning with a horrible rash on his hands and arms, presumably wounded by the plant that bites. Even his good right eye was swollen shut, from where he’d wiped his brow. Yellow pus ran like sap from his welted flesh. He bellowed when Mother tried to apply the salve. “I ask you, how did I earn this?” we heard him roar in their bedroom, through the closed door. “Ow! Great God almighty, Orleanna. How did this curse come to me, when it’s God’s own will to cultivate the soil!” The door flew open with a bang, and Father barreled out. Mother chased him with bandages but he batted her roughly away and went outside to pace the porch. In the long run, though, he had to come back in and let her tend to him. She had to bind his hands in clean rags before he could even pick up a fork, or the Bible.

Right after prayers I went out to check the progress of our garden, and was stunned to see what Mama Tataba had meant by hills: to me they looked like graves, as wide and long as a regular dead human. She had reshaped our garden overnight into eight neat burial mounds. I fetched my father, who came walking fast as if I’d discovered a viper he meant to behead. My father by then was in a paroxysm of exasperation. He squinted long and hard with his bad eye, to make out the fix our garden was in. Then the two of us together, -without a word passing between us, leveled it out again as flat as the Great Plains. I did all the hoeing myself, to spare his afflicted hands. With my forefinger I ran long, straight furrows and we folded into them more of our precious seeds. We stuck the bright seed packets on sticks at the ends of the rows-squash, beans, Halloween pumpkins-to remind us what to expect.

Several days later, once Father had regained his composure and both his eyes, he assured me that MamaTataba hadn’t meant to ruin our demonstration garden. There was such a thing as native customs, he said. We would need the patience of Job. “She’s only trying to help, in her way,” he said.

This is what I most admire about Father: no matter how bad things might get, he eventually will find the grace to compose himself. Some people find him overly stern and frightening, but that is only because he was gifted with such keen judgment and purity of heart. He has been singled out for a life of trial, as Jesus was. Being always the first to spot flaws and transgressions, it falls upon Father to deliver penance. Yet he is always ready to acknowledge the potential salvation that resides in a sinner’s heart. I know that someday, when I’ve grown large enough in the Holy Spirit, I will have his wholehearted approval.

Not everyone can see it, but my father’s heart is as large as his hands. And his wisdom is great. He was never one of those backwoods ministers who urge the taking up of copperhead snakes, baby-flinging, or the shrieking of nonsense syllables. My father believes in enlightenment. As a boy he taught himself to read parts of the Bible in Hebrew, and before we came to Africa he made us all sit down and study French, for the furtherance of our mission. He has already been so many places, including another jungle overseas, in the Philippine Islands, where he was a wounded hero in the Second World War. So he’s seen about everything.
