These represent the average taken from a number of places 

 in each region. In the mountain region it gives no adequate 

 idea of the temperature upon the upper slopes of the highest 

 mountains, where we have represented the Canadian fauna. A 

 table for Smithville, in the extreme south-eastern part of the 

 State, will illustrate how much warmer is such a southern point 

 on the coast.

In the mountain region, for example, we find on the higher 

 mountains as summer sojourners Wilson's Thrushes, Yellow- 

 throated Vireos, Rose-bi'easted Grosbeaks, Winter Wrens, Gol- 

 den-crested Kinglets, etc., which in the middle region are only 

 winter visitors, or only transients going to Middle America, 

 Northern South America, or the West Indies for the winter; 

 while some, the Towhee Bunting {Pipilo erythrophthalmus), for 

 example, are summer sojourners in the mountain region, tran- 

 sients in the middle, and winter visitors in the coast region, and 

 the extent of the State from north to south scarcely exceeds 2^ 

 degrees latitude! We cannot, of course, say that the same indi- 

 viduals spend the entire year in the State, but it would not be 

 singular if quite a number of the summer visitors to the mount- 

 ain region pass eastward with the approach of winter and reside 

 for the time in the coast region. 



While at Beaufort in the latter part of December, 1887, Cat- 

 birds (Galeoscoptes cavolinensis), Brown Thrashers {Harporhyn- 

 chus rufus), Towhee Buntings (Pipilo erythrophthalmus), were in 

 abundance, and evidently settled down for the winter. I was 

 told that they were common during the winter. 



Take such a point as Smithville, and we might expect to find 

 ((uite a number of winter visitors that are only known as ti'an- 

 sients in the middle, and summer sojourners in the mountain 

 region.
