* Mr. Leslie Brown, who was investigating the walia ibex in its precipitous home in the Simien Mountains at the same time, estimated the population at about 200 animals; of the females he could identify with certainty, more than half had kids. Their only enemy is man—he found no trace of leopards. Legal protection by the Ethiopian Government, he says, has not stopped the persecution in this remote area, but even two guards strategically placed could achieve much; the best solution would be to make the area a national park.
