| Description: | Even though the Crossett Experimental Forest is primarily known for its contributions to the study of naturally regenerated southern pine forests, it did play an important role in parts of the early tree improvement programs in the southeastern US. In this picture, Hoy C. Grigsby scales a ladder to the crown of one of the best pine trees found on the Crossett Experimental Forest. |

| Description: | Caption reads: "An example of hybrid vigor in southern pine. These are 1-1 seedlings raised in the Crossett nursery. All seedlings were less than 6 inches tall when transplanted last February. On the left: (1) are two seedlings of open-pollinated slash pine. From the same parent tree but pollinated with shortleaf are the seedlings (2) of a slash x shortleaf hybrid. No. 3 represents two seedlings of a shortleaf x slash cross which are taller than the two shortleaf pine controls (4). No. 3 and 4 are from the same parent tree. Hybrids No. 2 are 6 to 8 inches taller than the female parent controls and about 16 to 18" taller than the male parent controls. Note also the branchiness of the hybrids and their intermediate needle length. Pedigrees (1) A1-9 (C x wind); (2) A1-8 (C x E); (3) A1-10 (E x C); and (4) A1-12 (E x wind)." |
