AN entomologist's JUBILEE. 235 



But the Ichneumons, as he found, 

 Were like a sea -without a bound ; 

 ' This group is too confused,' said he ; 

 ' I iind it much too hard for me ; 

 How to determine this mass well, 

 Not Cuvier could, nor Linn6 tell.' 



But Gravenhorst at length was born, 

 To darkness now succeeded morn ; 

 The chaos left by former men. 

 He brought into a system then ; 

 And the Ichneumons first were known 

 Completely, through his work alone. 



But howsoe'er the work was tough, 

 His energy had not enough ; 

 Whate'er lays eggs, or suckles young, 

 Whatever crept, or flew, or sung, 

 Whatever leaps or swims the flood, 

 Has he compared, and understood. 



The living things in ocean's tide. 



And those the drops of water hide ; 



He studied all with energy, 



But chiefly Entomology, 



Though worms and reptiles well he knew, 



And many other creatures too. 



And what he knew, and thus could tell. 

 He taught it to his pupils well ; 

 Like grains of sand they throng around, 

 And he who in their ranks is found, 

 Goes well rewarded from the place, 

 And thinks upon his friendly face. 



Nature is kind, and loves him still, 

 And gives him what she rarely will ; 

 The strength of youth in green old age, 

 A pride to Science, truly sage ; 

 And whatsoever he has done, 

 God's blessing always rests upon. 



Fill, fill your bumpers to the brim ; 

 Our worthy friend, we'll drink to him, 

 The sage revered and loved by all. 

 Who teaches truth, whate'er befall ; 

 For fifty years he's laboured on : 

 Cry, ' Gravenhorst, hurrah ! ' each one."
