WITH a bovine calculation of the sag in the barbed wire, the cow butts the makeshift stake, and dips its head to enter. Allan Sealy comes alive. Strangled cries issuing from his throat, he takes off at a trot, bends at the waist, and essays the mock charge of a carnivore. The cow looks up mildly surprised. Sealy intensifies the snarls, and keeps bearing down. At rump-slapping distance, the cow takes a quick decision, pulls back its head and ambles off. Sealy straightens up, waits for it to cross the road, rights the stake ineffectually and heads back, an apologetic smile breaking on his face. He is embarrassed by his display of aggression, discomfited that he may appear acquisitive. But the tiny garden he has annexed from the municipal kerb in front of his house, and impregnated with a variety of saplings, is important. Both for reasons of environment and inspiration. Its regenerative rhythms, closely tied up with the seasons, are closely tied up with the Himalayas-based novel he is writing. And for Allan Sealy nothing is more important than his writing.
