Experience in crossing cucurbits, L. H. Bailey, M. S. (pp. 180- 

 187).— The anthor is engaged iu an extensive investigation on the 

 crossing of cucurbits. lie has already "made fully 1,000 careful hand 

 l>ollinalions, and obtained no leps than 1,000 tjpes of pumpkins and 

 scjuashes never recorded. The plantations of selections and crosses 

 covered some eight acres this year. The experiment is only begun. 

 The Miiiin results of it can not be announced until further work has 

 been done. But some of the incidental features of the research can be 

 stated from time to time." 



Ill this article several toi)ics are discussed as indicated below : 



(1) Immediate effect of Gw.s.sin(/. — "The 'immediate effect of crossing' 

 is a term used to denote any change which may occur in the fruit the 

 same year the cross is made, as a result of the influence of pollen. 

 Whatever effect the i)oIlen may have is usually shown iu the offs^jring 

 of the crossed fruit rather than imu:iediately, the same season, in the 

 fruit itself. There are but few plants in which an immediate effect of 

 crossing has been proved, and of these Indian corn is the most famil- 

 iar. It is commonly said that it occurs in pumpkins and squashes 

 also, but it certainly does uot. There has never been any immediate 

 influence whatever in any of our crosses, except such as was due to 

 imperfect development caused by insufficient or impotent pollen. In 

 other words, the effects of the cross are seen only in the offspring of 

 tlu' fruits. * * * 



"The same observation can be made with reference to blackberries and 

 raspberries. Over 250 successful hand pollinations were made this 

 year between blackberries, raspberries, and dew-berries in many combi- 

 nations, and there were no immediate effects." 



(2) Do jiumpkins and squashes mix f — " Before cousidering the ques- 

 tion, it is necessary to divide the fraits called sipiashes into two groups. 

 One group includes the summer and fall squashes, like the scallops, 

 common crook-necks, cocoanut, Bergen, and the like; these belong to 

 the same species as the field ]n\m\)k\n {GKcurbitd pcpo). These squashes 

 cross with the ordinary field pumpkin and with each other, although 

 even here the mixing does uot a[)pear to be indiscriminate. The other 

 group includes the Hubbard, Marblehead, Turbans, and so-called Mam- 

 moth squashes, and pumpkins like Mammoth Chili, and Valparaiso; 

 these belong to a distinct si)ecies (Guenrbita 7H((xima). Mau}^ careful 

 pollinations have been made between these two classes of fruits, and iu 

 no case have seeds been procured. Sometimes the fruit will develop 

 for a time, and in two or three iustancesa summercrookneck pollinated
