94 PRINCIPLES OF AMERICAN FORESTRY. 



Nut Seeds, as those of the Oak, Hickory, and Walnut, 

 should be handled as recommended for seeds with fleshy 

 coverings, but are more sensitive about being severely 

 dried. As they do not transplant readily, it is very 

 desirable to plant them where they are to remain 

 permanently. They should be covered about two inches 

 deep. 



Seeds of Leguminous Trees, as those of the Black 

 Locust, Honey Locust, and Coffee-tree, will stand severe 

 drying for a long time and still grow provided they are 

 treated with hot water just before planting. In this case 

 the hot water should be poured over the seeds shortly 

 before they are sown, and be allowed to stand until cool, 

 when it will be found that some of the seeds have swollen 

 up; these should be picked out and the remainder be 

 treated again with hot water, and the process repeated 

 until all have swollen. Seedlings of this class generally 

 transplant readily, and are managed in the same way 

 that is here recommended for the Ashes and Maples. 



Seeds of Coniferous Trees, such as Pine, Spruce, Tama- 

 rack, and Arborvitas, are dry and winged, but the Red 

 Cedar has a fleshy, berry-like covering surrounding its 

 seed. The seeds that grow in cones are most easily 

 gathered before being shed from the cones. The cones 

 should be gathered before they open, and then dried, 

 after which those of most species will open and the seeds 

 can be threshed out. Cones of a few trees, as those of 

 the Jack Pine, will not open without artificial heat. 

 These can be opened by gently heating them over a stove 

 or in an oven to a temperature of from 100 to 150 degrees 

 Fahr. Seeds of this class grow readily when sown, but 

 must be very carefully stored or they will lose their vitality. 

 They should be kept similarly to the seed of the Ash and 

 Box-elder, but are more liable to injury than these kinds 

 from too much moisture or heat, and for this reason
