them are largely, if not wholly due to pitch, intensity or the 

 presence of liquid consonants. 



Thus, all five of the factors, pitch, duration, intensity, pronuncia- 

 tion and quality, may be recorded on a single sheet by this graphic 

 method. The results, I believe, will be intelligible to musicians, 

 and a little less "like Greek" to those whose knowledge of written 

 music is slight. 



LIST OF THE BIRDS OF LOUISIANA. PART VII. 



BY H. H. KOPMAN. 



(Concluded from p. 29.) 



247. Western Tanager (Piranga ludoviciana) . The only known 

 record of the occurrence of this bird in Louisiana is a specimen taken on 

 March 19, 1898, by Mr. Andrew Allison in Jefferson parish, on the opposite 

 bank of the Mississippi river from New Orleans. It was a parti-colored 

 male, with yellow predominating. 



248. Scarlet Tanager {Piranga erythromelas) . This bird is seldom 

 very common in Louisiana except for a few days at a time. It is most apt 

 to occur at New Orleans about April 20 and in the early part of October. 

 The earliest date of arrival at the latitude of New Orleans is April 8, 1900, 

 at Bay St. Louis, Miss., and the latest date in spring is May 9, 1903, at 

 Lobdell, La. Considerable waves are sometimes present the latter part of 

 April, and about Oct. 10, 1896, I saw an unusual number in the suburbs of 

 New Orleans. The latest date of departure is Oct. 20, 1897, at Ariel, Miss. 



249. Summer Tanager (Piranga rubra rubra) . Common summer visi- 

 tor, especially in the higher sections of the State. In the swampy region 

 in the southeastern part it shows a disposition to frequent particular 

 neighborhoods, especially those which are better drained. The earliest 

 date of arrival in the latitude of New Orleans is March 31, 1902, at Bay St. 

 Louis, Miss. The latest date of departure is Oct. 27, 1899 and 1900, at 

 Covington, La. It is sometimes remarkably abundant at New Orleans 

 during waves in the latter part of April and early part of October. 



250. Purple Martin (Progne subis subis). Common summer visitor, 

 arriving usually about Feb. 15, becoming common about March 10, 

 and disappearing more or less completely from the southern part of the 

 State about Sept. 15. A large southward flight is usually noted at the Gulf
