practiced. Nine species in the colder regions of the 

 northern hemisphere. Staminate fls. small, globose to 

 oblong, solitary, consisting ot numerous short-stalked, 

 spirally arranged anthers; pistillate fls. larger, consist- 

 ing of several or numerous scales, with 2 naked ovules 

 at the base, each scale borne in the axil of a much longer 

 bract; cone with woody, 2-seeded scales, persistent on 

 the axis ; seeds with large, thin wings, ripening the first 

 year. Alfred Eehder. 



The European Larch is an upright, conical grower, 

 and one of our best lawn trees. In the spring, when it 

 is covered with its new growth of soft, feathery, light 

 green foliage, it is a very striking and beautiful object. 

 As it begins growth at a low temperature, it is the first 

 of our trees to be covered with new foliage. Again in the 

 autumn it is very beautiful, as its needles turn a golden 

 color before falling, for this tree unlike most of the 

 conifers, is deciduous after the hrst 

 year. In the middle West and along .^ !/i, 



the coast in Massachusetts, it is ^j 



planted for timber, shelter belt 

 and wind-breaks. Unlike its Anier 

 ican relative, L. Amerip 

 Tamarack, this tree grows on hif,h 

 ground and does well on a great va ' *-^ 



riety of soils. It does not do well ^ 



on low, submerged ground, the s , 



home of i. Americana. The Laich 

 is known in Europe as one of the most durable woods 

 It does not ignite easily, neither does it splinter, and the 

 wood was in great demand for these reasons for battle 

 ships before the ironclads displaced the wooden ships 



The Larch stands transplanting well, but this must 

 be done very early in the spring, before new growth 

 begins. The seed is sowti in beds of finely prepared 

 soil, about the middle of May, and either raked in or 

 covered very lightly by hand, not to exceed one-eighth 

 of an inch. It is usually sown in beds 4 feet wide. As 

 soon as it germinates it is shaded with lath frames, 

 raised about 10 inches above the bed. The first year it 

 makes a growth of from 2 to 4 inches, and holds its fo- 

 liage the first winter. A slight covering of hay or straw 

 should be lightly shaken over the seedlings as soon as 

 winter sets in, to prevent the seedlings being thrown out 

 by continual freezing and thawing. The frames are put 

 on again to hold the snow. During the following sum- 

 mer the frames should be removed entirely. At two 

 years old they will be from G to 20 inches in height, and 

 can then be moved to nursery rows or planted out per- 

 manently in the forest. The seeds should be sown 

 thicker than other conifer seed, as seldom over 60 per 

 cent germinate. Sometimes they make very little up- 

 ward growth the first and second years after trans- 

 plaiitiiiu'. si-ciiiiii^rlv |.uttinu .ill their strength into the
