ADLTTM, JOHN. Plate 11. Grape experimenter, and 

 author of "Memoir on the Cultivation of the Vine," 1823 

 and 1828, the iirst separately published American grape 

 book. Bomin York, Pa., Apr. 29, 1759. Died at George- 

 town, D. C, Mar. 1, 1836. He was a soldier in the Revo- 

 lution, major in the provisional army in the administra- 

 tion of the elder Adams, and later a brigadier-general in 

 the militia of Pennsylvania. He was also a surveyor 

 and civil engineer. He also held an associate judgeship 

 in Lycoming county, Pennsylvania, having been ap- 

 pointed by Gov. Mifflin. He was a friend of Priestly, and 

 endeavored to apply the scientific knowledge of his time 

 to agriculture. He early became interested in the ame- 

 lioration of the native grapes, and established an experi- 

 mental vineyard in the District of Columbia. He en- 

 deavored, but without success, to secure the use of cer- 

 tain public land in Washington for the purpose of " cul- 

 tivating an experimental farm." He brought the Ca- 

 tawba grape to public notice. He was a pioneer in the 

 awakening industrial activity of our new country. The 

 botanist, Eaflnesque, commemorated his name in the 

 pretty genus Adlumia ; but otherwise he has remained 

 practically unknown until very recently. For further 

 information, see Bailey, "Evolution of our Native 

 Fruits." L. H. B. 



ADLUMIA (from John Adlum). Fumari&cem. Ahardy 

 biennial vine, which climbs over high bushes in our moist 

 woods. Sow seed in spring in a damp, cool place. Trans- 

 plant in fall, if possible, if transplanted at all. It flowers 

 the first season.

 They thrive in full sun or partial shade; the perennial 

 species well suited for rockwork, borders, etc. Annuals

 in autumn or earliest spring ; perennials by seeds or 

 root divisions.

aiCHMilA (from aichme, point; referring to the rigid 

 points on the calyx). Bromelicieem. The ^chmeas are 

 closely allied to the Billbergias, from which they are dis- 

 tinguished by smaller flowers, which are little exserted 

 from the calyx and not widely expanding, short fllaments 

 and small anthers, sharp-pointed sepals and conspicuous 

 sharp-pointed flower-bracts. They are epiphytic herbs, 

 of about 60 species, natives of Trop. S. Amer. Flower-

 leaves, which are usually serrate ; petals 3, tongue-
