KALM'S VISIT 63 



that " in the largest orangery in Chelsea 

 Garden the smoke makes six bends in one of 

 the long walls before it escapes." 



" Orangery " seems to have been a common 

 name for the house into which the " tender 

 greens " were taken for the winter the " green- 

 house." 



On May i8th, Kalm again spends the morn- 

 ing at the Physic Garden. In the afternoon he 

 pays a touching visit to Sir Hans Sloane. Sir 

 Hans is in bed, aged-looking and rather deaf. 

 He approved highly of Kami's coming expedi- 

 tion to America, and thought it likely that he 

 would discover many new plants. Kalm 

 writes : " One and all looked upon this man 

 with a particular interest, because he was the 

 oldest of all the learned men now living in 

 Europe, whose names, on account of their 

 writings and learning, are widely known. We 

 find in the philosophical letters of that learned 

 man, John Ray, several letters which Sir Hans 

 Sloane had written as long ago as the year 

 1684, together with several of John Ray's 

 answers to them, from which appears what a 

 great insight Sir Hans Sloane had even at that 

 time (aged 29) into all branches of Natural 

 Science." 



Kalm pays two visits to Sir Hans Sloane 's 

 museum. Among other curiosities he is struck 

 by the way in which Hertfordshire " pudding- 

 stone," 1 which he must have seen used as 

 boundary stones on Berkhamsted Common, 

 can be polished to make " very handsome " 



1 In " Hertfordshire conglomerate " the matrix in which the 

 pebbles are embedded, like raisins in a pudding, is as hard as 

 the pebbles, and takes a polish.
