In 1929, the Cold Storage Company bought a 24 hectares stretch of forested land along Upper Bukit Timah. This area became known as the Dairy Farm Estate, named after the company's dairy farm, which supplied the supermarket with locally produced fresh milk. It was also the only European dairy farm with a herd of Friesian cattle specially brought in from Europe. Most of the workers on the farm were Indian cowherds and their children were educated at the Suthanthrothayam Tamil School located at Bukit Timah specially catered to these children. There were also Tamil dramas and entertainment shows staged around the 7th milestone, which were popular with the Indian community.
In addition to the Cold Storage dairy farm, there were also fresh milk sold on the hoof' by cowherds with cow in tow. These Tamil and Hindustani (or Uttar Pradeshi) cowherds would go from home to home peddling milk fresh from the source! They could also be seen with their grazing cattle in the open grassland between Sixth Avenue and Coronation Road behind the Chinese High School. However this ended in the 1970s when agricultural activities were rezoned by authorities away from Bukit Timah.
