ruarv and March. The flowers of the grafted |>hmts have been as large and as 

 beautiful as those of carnations on their own roots. En this work observations will 

 be made to determine whether the immunity acquired by grafting on Saponariais 

 inherited in the seedlings.

Experimental researches on the seed of orchids, A. Maumene (Jardin, 19

 Bernard, who showed that the presence of endophytous fungi in the embryo of the 

 seed of orchids is an essential condition to their germination.

FORESTRY. 



Influence of the origin of seed on the character of forest growth, A. Englee 

 (Mitt. Schweiz. Centralanst. Forstt. Versuchsw.,8 (1905), No. ?,pp. TV 81-286, pis. IS, 

 dgms. 2). — Different kind* of forest seeds were gathered in localities of varying alti- 

 tudes above sea level, and studied as regards weight, ability to germinate, and char- 

 acter of seedlings produced. The details are given in extended tables and discussed 

 at length. 



Some of the more important conclusions relative to the different kinds of seed are 

 as follows: The weight of spruce seeds and their ability to germinate decrease in 

 general with the height above sea level at which they are harvested. There is no 

 decided influence, however, up to L,200 to 1.400 meters. Seed- from high moun- 

 tainous districts do not germinate with as great energy as see. 1 from lowland- and 

 lose their ability to germinate sooner. 



The growth characteristics of highland and lowland Bprnce are inherited by the 

 seedlings, even when grown under different climatic conditions. Spruce grown from 

 lowland seed decreases in height growth with the distance above sea Level and at a 

 more rapid rate than spruce grown from highland seed. Bigh Alpine spruce is char- 

 acterized by a relatively large root development as compared with lowland spruce. 

 Seed from green cone.- produces the same kind of seedlings as seed from red cones 

 grown in the same locality. Large seed produces larger, heavier seedlings than 

 small <d'i\. 



Seed from Alpine regions when grown in low lam Is produce trees which start into 

 growth earlier in the spring, do Dot irrow so bigh, and stop growing earlier each 



season than trees grown from lowland seed. Seedling spruces from highland - 1 



are characterized by closer and shorter needles than those of low land Beedlings. The 

 structure of the needles to prevent drying out is also better. They suffer less in high 

 situations from early frosts, from destruction of the chlorophyll by too strong insola- 

 tion, and from breaking down by snow.
