CASE to the rostrum. Koch has figured and described (in his Uber- 

 sicht) another American tick, under the name of Ixodes Ameri- 

 cana (Acarus Nigua, Deg.) It is rounder and smaller, and is 

 probably more confined to the southern districts. This latter is 

 spoken of as being known in America by the name of piques, and 

 as being very distressing, and sometimes dangerous to man and 

 cattle. That it is very annoying is beyond doubt, especially 

 where men habitually sleep and live in the open air. 



Mr. Riley says of his species that it occurs in great abundance 

 at times on cattle in the West, and in Texas and Central 

 America, and that it had also been detected on a porcupine and 

 on a hare, which is confirmatory of the view we have above 

 taken regarding their habitat and habits. 



It is probably this tick to which Captain Campbell Hardy 

 alludes in his "Forest Life in Acadie " (1869). "A tick 

 (Ixodes) affects the moose, especially in mnter and early spring. 

 The animal strives to free itself from their irritation, by striding 

 over bushes and bramble?. The ticks may often be seen on the 

 beds in the snow, where moose have lain down, and whence they 

 are quickly picked up by the ever-attendant moose birds or 

 Canada jays (Corvus Canadensis). These vermin will fasten on 

 the hunter when backing his meat out of the woods. The Indian 

 says, 'bite all same as a piece of fire' " (p. 80).
