7. Flnt-groivn vs. Pot-grown Plants. — It is a question whether young 

 tomato plants thrive better in "fiats," — or shallow, tray-like boxes in com- 

 mon use among gardeners — or in pots. From each of two sowings of 

 Ignotum, made February 12 and March 14 in flats, two dozen uniform 

 plants were selected. One dozen, in each instance, were transplanted into 

 flats, and one dozen into pots, on the same days. The transplantings were 

 made as follows: 



Series I (eowa Feb. 12), March 4, April 4, May 5. 

 Series II (sown March 14), April 4, May 9. 



The flat-grown plants in each instance were set so far apart in the fiats 

 that the plants could not interfere with each other, and at the final trans- 

 planting they stood from three to four inches apart each way. The pot- 

 grown plants in the first series were transplanted into thumb pots and then 

 into 3-inch and 4-inch pots. In the second series, they were placed in 

 3-inch and 4-inch pots. The records are these: 



Table XII. — Flat-grown vs. pot-grown plants. 



The yields, in the second double column of figures, are decidedly in 

 favor of pot-grown plants, especially in the later sowing. And it may 

 also be said, although the table does not show it, that the pot-grown plants 

 gave earlier fruits. 



8. Seedlings vs. cuttings. — In 1890, seedling tomato plants gave twice as 

 heavy yields as cuttings of equal age. In 1891, seedlings gave earlier 

 fruits, and with one variety — Lorillard — the yield was also much greater 

 from seedlings, while in the Ithaca it was less. Secondary cuttings, that 

 is, cuttings taken from the cutting plants, gave much larger yields than 

 their parents, but the crop was much later. These experiments were 

 repeated this year. The stock from which all the lots of this year came 

 was one fine seedling plant of unknown parentage, of the peach type, 

 which came up in our forcing-houses. Late in winter, strong cuttings 

 were taken from the axillary shoots of this plant and were set out regu- 

 larly in our tomato house. In March, therefore, we had the one old or 

 parent plant, still in full vigor, which we shall call A, and a small brood of 

 cutting plants which we shall call, collectively, B. 



March 29, 12 cuttings were taken from A. These cuttings were three to
