berries promiscuously, were of different colors, some 

 Vvhite, and some of an orange color. But a second crop 

 of worms from the same cocoons, being fed exclusively 

 on the leaves of the morus multicaulis, finished their 

 labors in the short space of twenty-six days from the 

 commencement, which was about the thirtieth of July. 

 This last circumstance might be, in part, owing to the 

 warmth of the season. The cocoons thus produced 

 were not only of larger size than those of the first crop, 

 but what is still more important, they were beautiful and 

 shining, and of the lohiteness of Know. 



At the Fair of the American Institute of New York, 

 in 1833, cocoons were produced of two successive crops 

 of silk. The first crop were hatched the llth of May, 

 the second crop the 8th of July, and a third crop 

 might have been produced. All being fed on the morus 

 multicaulis, they were of a snowy whiteness. In the 

 same year, Mr. E. Stanley, of Ogden, N. Y., produced 

 two successive crops, the second was hatched by acci- 

 dent, and the cocoons were fine. In Brattleboro', Vt. 

 in the same year, two successive crops were produced 

 from the common white mulberry. And in 1834, as 

 Dr. Holmes has recorded, two crops of cocoons, both 

 of them large and perfect, were produced in Winthrop, 

 Maine. See his account in the Maine Farmer, vol. iii. 

 Feb. 20, 1835, published at Winthrop. 



In all these cases, the second crop of silk-worms was 

 produced from the eggs from the cocoons of the first 

 crop. 



Dr. Millington, of St. Charles, Missouri, has tried the 

 experiment with the most satisfactory success. He is 

 an eminently practical, scientific agriculturist, who has 

 made silk one of the principal objects of his attention 

 for several years. 



In his valuable communication in the American Far- 

 mer for January, 1829, he has stated, that the eggs of 

 the same year hatch but partially, or do not hatch so 

 regularly and simultaneously as those of the former year. 

 He notes the date and the day the eggs are produced,
