pickings during the season, and continue longer in bearing, than 

 the extreme early and late sorts, hence give a greater total yield. 

 Those varieties of strawberries that produce pollen and berries also, 

 are at a disadvantage as corcpared with those that produce ber- 

 ries only. Division of labor counts here as elsewhere. Give a 

 plant nothing to do but to grow and bear fruit, and the work will 

 be better done than if an additional task is imposed. To produce 

 pollen taxes the energies of the plant much ruore than is commonly 

 supposed. Many growers think it would be desirable to have 

 varieties with perfect blossoms only to save the trouble of planting 

 the two classes. Theory disproves this plan ; and careful observa- 

 tions show, that, in general, the most prolific sorts are those that 

 have imperfect flowers. It should be understood that these state- 

 ments refer to the leading varieties that are most generally grown. 

 There are some apparent exceptions even with these, and still 

 more if all known varieties are included.

 the Holy Land with notebook and camera, is about to publish the 

 results of his wanderings in a work entitled "In Scripture Lands." 

 It is to be issued at an early date by the Scribners. A new work 

 of practical value, entitled '• Electricity in Daily Life," is also 

 about to be published by them. It is a popular account of the 

 application of electricity to every-day uses. The various branches 

 of the work have been intrusted to writers selected for their ex- 

 pert acquaintance with the subject. A life of John Ericsson will

 many years, and has been intrusted with the famous inventor's 

 papers and correspondence. It will be profusely illustrated.

It is only within very recent years that this 

 department of research iias been cultivated; and 

 it IS natural that the results of different workers, 

 involving variations in method and design, 

 should show points of difference. In spite of 

 these it seems possible to present a systematic 

 sketch of vvliat has been done, with due reference 

 to the ultimate goal as well as to the many gaps 

 still to be filled.
