Fruit rot (i>p, 15*.>, 1<!0). — Facts from the experience of the authoi-are 

 cited which indicate that vigorous i)hints, early setting, and es])ecially 

 upright and open training will diminish the amount of rot. 



Kccpiixj qualities of toiiuitocs ([ip. I(n-l(i4). — The taluihitcd results of 

 keeping tests of a number of varieties in ISS!) in the sunlight in a forc- 

 ing house, and in 1891 iu a cool, dry room, without sunlight, agree in 

 indicating that the small and conii)aratively unim])ortant varieties will 

 keep the longest; but that in general keeping quality is not connected 

 with solidity or varietal ditterences.

 tomatoes grown in the fertilizer experiments above referred to gave the 

 following results:

Grosses (pp. 165-168). — In the winter of 1890-91 a few successful 

 hybridizations were made between the Ithaca {Lycopersicum esculentiim) 

 and Currant {L. pimpinell/ifolium) tomatoes. The parents and hybrids 

 are described and illustrated. Brief accounts are also given of crosses 

 made between red and yellow varieties and between purple and red 

 varieties. 



The hybrid between Ithaca and Curraut was iutermediate betweeu the parents, 

 and produced fruits four times the size of the Currant in clusters of from 6 to 14. 



Crosses betweeu yellow and red tomatoes, the yellow being the pistillate or seed 

 parent, uniformly gave red fruits; and crosses between purple and red varieties also 

 gave red fruits. 



Crosses between the large leaf and common type of tomatoes (Mikado and Igno- 

 tum) gave foliage of a peculiar type intermediate between the two. This peculiar 

 foliage is also a characteristic of Ruby Queen. 



Bo tomatoes mix in the field f (pp. 68-171).— ^" Two or .three plants of 

 each of 6 varieties were set closely together in a row, all the plants of 

 each variety being together. The varieties and the order were as 

 follows: (1) Potato Leaf, (2) German Kaisin, (3) Golden Queen, (4) 

 Favorite, (5) Jaune Grosse Lisse, (6) Mansfield Tree. * * * Several 

 fruits were saved from each variety and a few plants were grown 

 from them." A record of the results is given. These indicate that 

 "tomatoes mix in the field, and even hybrids with the Currant type of 

 tomato may arise spontaneously. Eed tomatoes sometimes come from 

 yellow and purple fruits. It is therefore e%adent that seeds should be 

 selected fiom plants which are somewhat removed fiom other varieties."
