IjOte Sowing.—In the cane of the Tumi') Flea-l)ectle, Fletcher states in Bulletin No. 52 of the Kxpared, and the young plants grow rapidly and produce as good crops as when sown three weeks earlier. Clean Culture.—In view of the fact that flea-beetles in the larval state feed upon the roots of common weeds such as the nightshades, thorn apple, lamb's quarters, pigweed, ragweed, etc., it is important that such we^ds be pulled and burned. If this is done about the middle of July, large numbers of the grubs will be destroyed. Weeds along margins of fields, of course, should Ik* kept down. It is a wise practice to use land infested by such weeds for crops which are not attacked by the adult fiea-bectles. It is also important to remove from fields and garden.^ in the fall all remnants ofcrops, such as cabbage stumps, leaves and tops of turnips, etc. and other refuse which would serve as hibernating shelters for the adult Hea-bcctles. All such refuse should be either ploughed deeply or carefully gathered up in piles and burned. THE COMMONER SPECIES OF FLEA-BEETLES. The Spinach Flea-bgetlf, {Disony
