Edward Moorhouse, Dictionary of National Biography… (1912)
“ Nature had endowed Watts with the best of ‘hands.’ Perhaps he was seen to chief advantage on an inexperienced two-year-old, employing gentle persuasion with admirable effect, although he was equal to strenuous measures at need. In 1900 Watts began to train racehorses at Newmarket. That season he only saddled one winner of a 100l. plate; but in 1901 he turned out seven winners of fifteen races worth 5557l., and in 1902 four winners of five races valued at 1327l., between March and July. ”
