Were the diamonds said to be found at the Cape, and sent to England, really found in South Africa? I have just returned from the so-called diamond district, to which country I proceeded from England, being deputed by Mr. Harry Emanuel, the diamond merchant, of Bond-street, who is well known as a most indefatigable scientific enquirer on the subject of precious stones, and who naturally felt a great desire to develop a new source of supply of a commodity in which he is so largely interested. During the time I was in South Africa I made a very careful and lengthened examination of the district where the diamonds were said to have been found, but saw no indications whatever that would warrant the expectation of the finding of diamonds, or of diamond-bearing deposits, at any of the localities.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
