maple lands of Pennsylvania and New York as a source of general sugar supply for the United 

 States. Although negligible from this point of view, maple sugar was of great importance 

 among the colonial settlers and the Indians, as shown by quotations from early accounts as 

 far back as 1684, in regard to the making of sugar from the "juice of the maple."— .4. C.

1701. GuNTHER, R. T. The garden of the Rev. Walter Stonehouse at Darfield Rectory, 

 in Yorkshire, 1640. Gard. Chron. Ill, 67: 240-241, 256, 268-269, 296. Fig. 116, 137. 1920.— 

 Stonehouse was a friend and correspondent of William How, author of Phytologia Britannica 

 (1650). He was established at Darfield in 1631, but after 1644 forcibly ejected by the Parlia- 

 mentary Commissioners and imprisoned; he died in 1655, aged 58. Among the manuscripts 

 of Magdalen College are 2 lists of plants grown at Darfield in 1640-1644, which are printed 

 herewith; also plans of the garden and saffron garth in 1640. Stonehouse estimated the num- 

 ber of his plants as 866 in 1644, and they included 14 species from Virginia, 5 from Guinea, 

 and 4 from New England. [See also Bot. Absts. 7, Entry 699.]— M. F. Warner. 



1702. H[all], a. D. Spencer Pickering. Nature 106: 509-510. 1920.— Percival Spencer 

 Umfreville Pickering (1858-1920) began his scientific career as a chemist, brilliantly demon- 

 strating the hydrate theory of solution. His most important work, however, has been on the 

 scientific problems of fruit growing, notably the poisonous effect upon trees of the root- 

 excretions of grasses. Science and Fruit Growing, published in 1919, embodies the results 

 of the Woburn experiments since 1896. — M. F. Warner.

 1722-Nov. 5, 1801) was founded in 1773 near the present village of Marshallton in Chester 

 county. Many large trees are still standing which were planted by him, and which furnished 

 practical knowledge for his Arbustrum Americanum: the American Grove (Philadelphia, 

 1785). The article is illustrated with photographs of some of these old trees and views of 

 Marshall's house. — M. F. Warner.
