when set, and the rootstock should show two nodes at the base. 

 The arrangement and closeness of the planting vary greatly under 

 different conditions. Most commonly the plants are set at 1-foot 

 intervals in rows from 1| to 1| feet apart. The dune is kept in 

 suitable form chiefly through the arrangement of the planting. 



Kellogg 1 reports the following procedure in establishing beach 

 grass on the Pacific coast. The grass is planted between Sep- 

 tember and March when the sand is moist. Two-year old plants

them into sections with one or two nodes on each piece. They 

 are set out in rows from 12 to 18 inches apart at right angles to 

 the prevailing wind, the plants of one row alternating with those 

 of the next. The planters usually work in pairs. One man in- 

 serts a long, straight, heavy spade into the wet sand and presses 

 it to one side, thus making a V-shaped opening. The other inserts 

 from 2 to 4 plants into the opening which is closed by the first 

 man inserting the spade at one side and pushing the soil firmly 

 against the plants (Fig. 33).
