Abstract
Electron micrographs show that tubular halloysite is present in the red-brown (No. 60) and yellow-brown (No. 50) soils in Barbados and also in the St. George's Valley association ( No. 20) which contains material washed in from the Nos. 60 and 50 soils. No halloysite was seen in other samples. The high plastic limits show that the halloysite is present in sufficient amounts to influence the physical properties of the soil.
