Received Smith's letter of 24 [March 1825]. Pleased Smith approves of his "Hortus Ericaeus"; they took great pains to ensure accuracy and hope that the diagram will prove useful; Mr Hayter intends to draw up an enlarged "illustration of its uses" to present to Royal Society. Willow cuttings sent by Smith safely received; they will form foundation of the willow garden he intends to make. Will be pleased to show Smith his collection of heaths when he has leisure to visit Woburn [Abbey, Bedfordshire]. Pleased to hear Smith is busy completing the third volume of his "[English] Flora".
