The Diary of Weng Tonghe is found to be a unique and very substantial historical document, which provides contemporary reports of dust storms in Beijing over 1860—1898 A.D. After collating and examining these entries scattered through the book, what emerges is a body of records of dusty days in Beijing at that time. Accordingly, the time series of the annual and Mar.~May number of dusty days in Beijing over 1860—1898 A.D are reconstructed. The average annual and Mar.-May number of dusty days in Beijing during 1860—1898 AD are about 11 days and 7days respectively. Both of them seem to be a little lower than those at the present. However, the monthly distribution of the dusty days in Beijing agrees well with that at the present. The season and month with the highest number of dusty days are spring (March~May) and April, respectively.
