Many varieties of grass seeds are short in supply — better cover your wants now. 



August, September and early October are the right times to sow grass seeds.

MICHELL'S SEED HOUSE, 



preparation of lawn grass seed, and 

 when ordering you should say whether 

 the soil is a clay loam or sandy, wheth- 

 er it is boggy or moist, or high and 

 dry. 



The fine mixtures of the seedsmen 

 are all right and a few dollars are of 

 little consequence in such an impor- 

 tant and permanent undertaking as 

 making a lawn. 



Most of the grass seeds are very 

 light and will fly in every direction, 

 much preferring the openings in your 

 face to the ground. When there is a 

 very gentle breeze blowing steadily in 

 one direction is a good time to sow. 

 You will soon find out then where your 

 seed is settling and gauge your dis- 

 tance accordingly. About thirty to 

 forty pounds of grass seed are usually 

 sown to the acre and five or six pounds 

 of white clover. 



If a small plot of ground, it is easy 

 to know when you have sown enough. 

 And don't be afraid of sowing too 

 thickly. There may be two little plants 

 spring up where one would do, but it 

 will be a case of the survival of the 

 fittest. The stronger will crowd the 

 weaker out. Therefore, sow plenty of 

 seed. Neither in spring nor fall is it 

 advisable to keep the newly made 

 lawns mowed closely, so you must 

 waive appearance for the benefit of 

 the grass, at least for the first season. 



THE ASH TREES. 



Prof. Sargent has an interesting ar- 

 ticle about ash trees in one of his 

 recent bulletins. It reads as follows: 



Fraxinus is the name of the genus to 

 which all ash trees belong, although it 

 may be well to say that the trees called 

 Mountain Ashes are not ashes but be- 

 long to the genus Sorbus, a member of 

 the Rose Family and closely related to 

 the Pears, Apples and Chokeberries. 

 Ash trees occur in nearly every tem- 

 perate part of the Northern Hemis- 

 phere, but are more abundant in spe- 

 cies in eastern North America than in 

 other parts of the world. Ash trees 

 fall naturally into two groups; those 

 of the first group are furnished with 

 narrow white petals (Ornus) and the 

 flowers of those in the second group 

 are destitute of petals. 



The best known tree of the first 

 group is the little tree called Manna 

 Ash or Flowering Ash (Fraxinus Or- 

 nus) a native of southeastern Europe 

 which has long been an inhabitant of 

 the gardens of western Europe. It 

 grows well in the middle Atlantic 

 States, but has never been a success in 

 the Arboretum where a tree which had 

 flowered in 1917 was killed to the 

 ground by the extreme cold of the fol- 

 lowing winter. Three of the flowering 

 Ashes are natives of the United States, 

 Fraxinus cuspidata and F. Greggii of 



the Mexican boundary region and F. 

 dipetala of the mountain valleys of 

 California. These three plants are not 

 in the Arboretum collection where 

 they would not be hardy, but Ornus is 

 well represented here by two eastern 

 Asiatic species, Fraxinus Bungeana, a 

 small shrub from northern China 

 which was first raised here in 1882, 

 and by the Japanese Fraxinus longi- 

 cuspis which grows in the Arboretum 

 both as a shrub with several spreading 

 stems and as a small tree. 



Of the Ash-trees without petals and 

 therefore with inconspicuous flowers 

 there are seventeen species with a 

 number of more or less distinct varie- 

 ties which are natives of the United 

 States. Six of these trees grow in the 

 northeastern part of the country and 

 three of them are common New Eag- 

 land trees. To these trees color names 

 have for no very obvious reason been 

 given, at least in books, for it is 

 doubtful if these names have any gen- 

 eral application among persons whose 

 knowledge of trees has come from an 

 intimacy of association with them in 

 the forest or by the roadside, and not 

 from the study of other persons' ideas 

 about them recorded in printed pages. 

 To persons who know trees from 

 books White Ash, Black Ash, Green 

 Ash, Red Ash and Blue Ash are fa- 

 miliar names.
