8 THE AMERICAN BOTANIST 



yield has been 1741 quarts an acre for the last six years and 

 would have been still higher except for the almost total failure 

 of the crop in 1910, because of late spring frosts. The ber- 

 ries brought an average price of fourteen and one-half cents 

 a quart. Allowing for interest, taxes and depreciation, the 

 annual profit is reckoned at $116 an acre. Agricultural ex- 

 perts recommend that the most promising wild bushes be 

 selected for size, flavor, color and early ripening and then be 

 transplanted. The aim is to produce wild berries that are 

 easy to pick and that sell for a higher price than the smaller 

 ones. Berries 11-16 of an inch in diameter, are not uncom- 

 mon now. Blueberries thrive best in soils so acid as to be 

 considered worthless for ordinary agricultural purposes. 

 Raising them, therefore, promises to add to the general wel- 

 fare through the utilization of otherwise valueless land. 



FRAGRANT WILDFLOWERS 



By C. L. Gruber. 



DURING 1917 I tested the fragrance of about 250 species 

 of flowers and the following list comprises those spe- 

 cies which I found fragrant to a greater or less degree. 

 The omission of species known to be fragrant, simply means 

 that I did not have the opportunity to test them during the 

 season of 1917. In the appended list: 



(a) Means very fragrant, (b) means fragrant and (c) 

 means slightly fragrant, (a-b) means usually very fragrant, 

 but sometimes only fragrant, while (b-a) means usually fra- 

 grant. 1)ul sometimes very fragrant: similarly for (b-c) and 

 (c-b.) 

 The following obesrvation may not be out of place: 



1. Flowers must not be too old to test their fragrance.
