Only three times since that day had she been to this part of the Dwellers’ province, and on those occasions it had been to take Fuchsia for the long walks that at one time she had so insisted upon, rain or shine.

Mrs Slagg’s days of long walks were over, but she had on one of those occasions passed the mud huts when the Dwellers were having their last meal. She knew that the Dwellers always had their supper in the open, at tables that reached in four long rows over the drab, grey-coloured dust. In this dust, she remembered, a few cactus trees were alone able to take root.

Following the gradual decline of a scarred green that sloped from the arch in the wall and petered out into the dust upon which the hovels were built, she saw suddenly, on raising her eyes from the path, one of these cactus trees.

Fifteen years is a difficult depth of time for an old woman’s memory to plumb – more difficult than the waters of her childhood, but when Mrs Slagg saw the cactus tree she remembered clearly and in detail how she had stopped and stared at the great scarred monster on the day of Fuchsia’s birth.

Here it was again, its flaking bole dividing into four uprights like the arms of a huge grey candlestick studded with thorns, each one as large and brutal as the horn of a rhinoceros. No flaming flower relieved its black achromatism although that tree had been known long ago to burst open with a three hour glory. Beyond this tree the ground rose into a little dreary hill, and it was only when she had climbed this hill that Mrs Slagg saw before her the Dwellers at their long tables. Behind them the clay huts were huddled together in a grey swarm, spreading to the foot of the wall. Four or five cacti grew between and reared over the supper tables.

The cacti were similar both in size and in the way they split into high uncouth prongs to the one which Mrs Slagg first saw, and as she approached, were edged with the hot afterglow of the sun.

At the line of tables nearest the outer wall were ranged the elderly, the grandparents, the infirm. To their left, were the married women and their children whom they were tending.

The remaining two tables were filled with men and boys. The girls from the age of twelve to twenty-three had their meals in a low mud building on their own, a few of them being delegated to wait each day upon the ancients at their tables immediately under the battlements.
