INJURIOUS AND BENEFICIAL INSECTS. 249 



is ill search of it at an early hour, ere the warmth of the sun 

 gives it warning to retreat. But the Goldsmith grub can be 

 taken at any hour of the day simply by scratching away the 

 earth from around the roots of those plants whose dark, shriv- 

 elled leaves tell of the enemy's presence. It is my belief that 

 this devastation might have been spared by an outlay of from 

 $20 to $30 for labor, of which, under proper direction, much 

 could have been done by children. Therein would have been 

 saved a strawberry crop for the ensuing summer, worth 

 scarcely less than $2,500, for from this same farm the crop of 

 a single acre has been sold for $1,500. Then, however valu- 

 able such labors are in the immediate results, that is but a 

 fraction of their worth as respects the future. These cotalpa 

 grubs, with all their mischief, had not more than a third of their 

 ultimate size ; hence their real ravenousness is yet to come. 

 Besides, what a prospect of increase of numbers, should even 

 a moderate share of them reach maturity ? Why should not our 

 farmers seek to know something about their insect-enemies, 

 and when practicable put forth some energy to meet as such ? " 



Snails Injurious to the Strawherry . — Under this caption 

 Prof. E. T. Cox publishes in the "American Naturalist," 

 (vol. II., p. QQQ)^ a note regarding the injury done in Indiana 

 by a little snail (Pupilafallax), at present found occasionally 

 though not abundantly in this State. Though this report 

 refers chiefly to insects, yet gardeners are undoubtedly in 

 the future, as civilization advances and the country becomes 

 more thickly settled, destined to be plagued by these little 

 animals, and a slight notice of them may not be out of place, 

 as the ravages they commit may be sometimes wrongly attrib- 

 uted to insects. 



It seems that Mr. and Mrs. Chappelsmith of New Harmony, 

 Indiana, "found their strawberry-plants dying rapidly, and 

 on seeking for the cause discovered these molluscs at work 

 upon the stems and crowns of the plants, rasping ofl" the 

 outer coating, and sucking their juices in such a manner as to 

 cause them to decay. Mr. C. found as many as forty upon 

 one plant, and thinks they have killed several thousand upon 

 the different beds. Though more abundant on the straw- 

 berry, he has found them on a variety of plants. Since atten- 

 tion has been called to the depredations of these minute mol-
