all off.” “ The deuce! You have done much mischief 
with your officiousness,” answered Linne; but what 
was done, was done, and Linne’s hope of establishing 
the cochineal in the orangery was blasted. This 
troubled him so much, that he had megrim forthwith; 
one of the severest attacks he had ever experienced. 
In consequence of Linne’s exertions many trees of 
Russian and North American origin have been widely 
distributed, many of them being now common in 
parks and gardens, such, for instance, as Vitis 
hederacea , Virginian creeper; Acer Negjmdo , ash¬ 
leaved maple; Ptelea trifoliate ,, shrubby trefoil; 
Dielytra spectabilis , bleeding heart; and many more. 
Of special importance were many of economic value. 
Naturally the majority of visitors to the garden were 
Swedes, but eminent men coming from foreign 
countries found Linne an entertaining guide. Among 
them may be named Frederick Calvert, Lord Balti¬ 
more, who came in 1769, and was so delighted at the 
sight, that he not only sang Linne’s praises in his 
“ Gaudia poetica,” but also sent him a splendid gold 
snuff-box of 100 ducats in value [^48] and a “ neces- 
saire ” of silver yalued at 12,000 dalers [^300]. By 
1744, the requirements for heating the stoves amounted 
to sixty loads of wood from the University forests, and 
nine furnaces were installed, in place of the five 
previously existing. The labourers in the garden, 
through Linne’s influence, had their wages doubled. 
For the maintenance of the garden with very 
restricted means, a skilful and trustworthy gardener 
was essential. He had such in the person of Nietzel 
(see pp. 153, 188), who worked till his death in 1756. 
Through Linne’s efforts Nietzel had not only his 
salary raised, but received the title of “ Inspector ” to 
distinguish him and to assimilate his position to that 
of “ Exercitie ” master in the University. A further 
instance of the esteem in which he was held is, that 
when he left behind him a weak-minded widow, who 
had caused him great trouble, and a young daughter,
