A prominent importer, broker, wholesaler and retailer of tea in late Victorian times, this company published a catalogue describing its operations. There are sections describing the Mincing Lane Market in London, which at that time handled sugar, coffee, tobacco, spices, cocoa and wine, as well as tea! Within its pages, there are also sections describing how tea is grown, processed, transported to destination and made available to its customers.
The full catalogue can be reviewed in full on line by visiting the Internet Archive https://archive.org/details/b30477426.
An interesting look back in time!
