Ferns grow naturally in a soil com¬ 
posed largely of Leaf-Mold. We are

mixed with the soil to the depth of 
several inches. It retains moisture, 
and also greatly benefits the condi¬ 
tion of the soil. 2-bus. bag $2.50.

PINE NEEDLES. These are 
very useful for a mulch around 
acid-loving plants, such as Trailing 
Arbutus and Cypripedium acaule. 
Pine Needles may also be mixed to 
a depth of several inches in the soil 
where one is going to plant any of 
the acid-loving plants, particularly 
the Cypripedium acaule. These 
Pine Needles will be partially de¬ 
composed, and are ideal for the 
purpose intended. Price per 2-bus. 
bag, $1.00; 10 bags $5.00. By ex¬ 
press or freight only.
