During these eight years, Lucy’s health, after some fluctuations, had decidedly improved; and when her husband was preparing to return in the autumn of 1907 for his final round-up of the Happy Valley Concession, she insisted on accompanying him. It would be for less than two years; Maud was coming too; and the children would be most of their time at school. Rather with misgivings Roger agreed. Provided she kept her health, it would indeed be a delightful conclusion to the great adventure of their lives. They would revel for the last time in the beauty of Iraku and the Happy Valley, their Crowned cranes and pea-fowl, their tame gazelles and duikers, their quaint menagerie of monkeys; their wonderful flower garden—Iraku grew everything: orchids and mignonette, roses and lilies, petunias and pelargoniums, _Strelitsia reginae_ and _Disa uniflora_.... He would wind up his financial connexion with the Concession and retire from it a rich man, perhaps retaining a sleeping partnership in its concerns: for it was entangled with his heart-strings. Then, all clear for Europe, after a cycle of Cathay. They would motor from Iraku to the nearest railway station on one or other of the lines that now penetrated the interior, secure the best cabins on the luxurious steamers of the D.O.A. line, and thus retrace the route of their first voyage, when love was incipient, but when their future seemed dark and uncertain. They would be lovers again on this voyage, but this time open and unashamed, and Maud should pretend to play the part of a green-eyed Mrs. Bazzard. The first portion of this pleasant programme was fulfilled. For a year Roger rode from factory to mine, from coffee plantation to the fields and sheds where pineapples were grown, cut, and canned. He made good suggestions about their cattle, about war, unceasing war on the tse-tse fly, which—it was feared—was entering the Valley. He viewed with satisfaction his success over the crossing of Maskat donkey and Basuto pony mares with zebra stallions, and considered it proved that the resulting mules might become a valuable factor in East African transport. He inspected the new ostrich farms, the new smelting works and the primitive ceramics where native women turned out excellent pottery for home use. He decided that further explorations for gold should be undertaken in Ilamba, and that a fresh reef should be opened up in western Iraku. They would waste no more money looking for the matrix of the diamonds—diamonds might go hang, there were plenty of them in German South-West Africa. But this wolframite with its product tungsten: _that_ was worth following up with persistence. It was more and more needed for the application of electricity and for the latest developments of metallurgy, and would alone make the Concession of great monetary value.
