It was not an enviable escape at first sight. The house at Lambeth was a grand house, set among its own twenty acres of nursery garden, famous for its collection of rarities from all around the world. His father, John Tradescant, had named it the Ark, and had sworn they would be safe there whatever storms rocked the country with king and Church and Parliament all set on different and opposing courses. There were half a dozen bedrooms and the great room for the rarities, a dining room, a drawing room and a kitchen. A little son, Johnnie, to inherit it all and his older sister Frances to insist on her own claims. These riches J had exchanged for a single five-foot, four-inches-long bunk built into the damp wall of the ship. There was no room to sit up, barely room to roll over. He had to lie on his back, feeling the huge movement of the waves lifting and dropping him like driftwood, looking at the planks of the bunk above him. To his right against the skin of the ship, he could feel the slap of the waves and the whisper of their ripples. To his left was the slatted door for which he had paid extra for the little space and privacy it gave him. The other, poorer emigrants slept side by side on the floor of the ’tween deck like animals in a barn. They had been loaded like baggage into the waist of the ship with the crews’ quarters at the stern behind them, and the captain’s tiny cabin and the cook’s galley and cabin – all in one – in the prow before them.

The captain would not allow passengers out on deck except for the briefest and most grudging spells in fine weather. The crew going on watch trampled over the passengers and, when they were returning to their shared hammocks in the stern, dripped water all over them. The emigrants were always in the way, they were regularly cursed, they were less than cargo.

Their bundles and boxes were piled up among their owners in a careless muddle; but as the days wore on into weeks families established their own little seats and bunks out of crates of chickens and bags of clothes. The stench was appalling. There were two buckets provided, one for washing water, one for excrement, and there was a strict rota for emptying the soil bucket over the side. The captain would not allow them to do this more than once a day and when it was J’s turn to carry the brimming pail to the side his stomach heaved.

There was scarcely enough water to drink, and it came warm and tasting of the barrel, there was hardly enough food. A lumpy porridge for breakfast, the same for dinner, and a biscuit and a slice of old cheese at night.
