time must elapse in order that planting may be carried on 

 before growth starts in the nursery. Therefore, a northern 

 slope sufficient to retard growth slightly is a desirable 

 feature in a location. Pro sty or low lands are dangerous, 

 as vinter heaving and early and late frosts are two evils 

 that are prevalent in our climate. 



IV. A soil of a loaay nature fine enough 



to retain moisture and yet not be wind-carried is necessary. 

 Clayey soils arc difficult to work, cold, and excessively 

 heavy. The post-glacial marine deposits along the Gt. 

 Lawrence and other lake and river valleys are especially 

 suited to nureery requirements. 



V. A dependable water supply nearby to 

 furnish a natural reservoir ia required. As water nust be 

 delivered throughout the nursery with tap pressure, the 

 tank is placed on a natural or artificial eminence of at 

 least forty feet in height. 



VI. If the nursery is not partially 

 sheltered in periods of drought, the mortality is seriously 

 increased by wind. In the spring, especially in the newly- 

 transplanted treee and in the seed-bede, this is dangerous, 

 as the young growth is very tender. If natural wind-breaks 

 are not available, artificial shelters of rapidly-growing
