Indiana, size and frequency of occurrence, distribution by counties in the State, the economic 

 uses and horticultural value, and, in some cases, the best methods of planting. — There is also 

 an interesting table of measurements on largest trees of some species occurring in the State. 

 The author is preparing a book on the trees of Indiana. — W . D. Slerretl.

947. Greterz, H. von. Das hagel-, Ton-oder Mandliholz. [The identification of the 

 spruce (Picea excelsa, Lk.).] Schweiz. Zeitschr. Forstwesen 70: 86-89. 1919. — The great de- 

 mand for forest products during the war led to a much closer utilization of inferior material 

 than heretofore. In handling this material definite characteristics were noted in regard to 

 the wood markings and structures. Wood from the Horn state forest showed an outer struc- 

 ture that was crenate. The notches were 0.5 to 2 mm. deep and 1 to 3 mm. long, arranged 

 on the stem similarly to the cell structure on the interior. This crenate formation was never 

 found at the center of the stem, nor in trees under 40 cm. in diameter breast high. The for- 

 mation is always directly correlated with the medullary rays. In cross examination this 

 crenate formation can be very distinctly noted in the annual rings, which show a wavy ar- 

 rangement. — The technical properties of the spruce are more pronounced at higher elevations 

 than at lower ones, although in other species the stunted growth and increased number of 

 branches at higher altitudes decrease the technical value. No definite information was noted 

 for the different exposures. — This article is illustrated by microscopic photographs of cross, 

 tangential and longitudinal sections. Also the crenate formations on the outside are illus- 

 trated. — J. V. Hofmann.

 bruk 27: 65-67. Mar -Apr., 1919. — Hazel sprouts of suitable sizes so as to allow splitting in 

 two parts are extensively used for slack cooperage. Willows are also used but are not as good 

 as hazel. — J. A. Larsen.
