actual cost of collecting seed from the trees where logging is in oper- 

 ation is considerably less. The month of October is the most favor- 

 able time for collecting seed, which should be done before the cones 

 (" balls") are sufficiently ripe to open or fall off when the tree is 

 felled. Where no logging is in progress seed may be gathered by 

 climbing moderate-sized trees where cones can be reached by hand. 

 Lineman's climbers are useful in this operation. Various devices may 

 be used for collecting the cones beyond arm's length. After being 

 picked the cones should be spread on trays, screen, canvas, or tight 

 floors to dry. 



Young seedlings show exceptional vigor and are transplanted with 

 the greatest ease, provided soil moisture is plentiful. The root system 

 is comparatively shallow. In the dryer natural situations the tap-

root even in young saplings has been found to extend downward for 

 several feet. In the dryer nursery soils it is essential to supply abun- 

 dant moisture, and mulching will prove very helpful. Additional 

 growing space may be required if the seedlings are kept in the nursery 

 during the second season. If the seedlings are transplanted in the 

 nursery, a spacing of 2 to 4 inches in rows 4 to 8 inches apart will 

 probably be about right in most soils during the second season. 



The hardiness of cypress seedlings in the Northern States depends 

 somewhat on where the seed was grown. Louisiana and Florida seed, 

 for example, have been found to produce seedlings less able to stand 

 the cold winters than seed from the more northern portion of the 

 range. 1 The amount of seed from more northern regions is limited, 

 however, by the failure of cypress to mature seed to any considerable 

 extent over the extreme northern portion. At New Haven, Conn., 

 it has been found impossible to collect fertile seeds from trees growing 

 in the locality, while perfectly hardy cypresses have been grown from
