 Loam, clay and K2SO4 (NH^^ SO,, PgOs and char- 

 coal The plants varied considerably in the rapidity and 

 amount of ^heir growth. The difference i" frag™nee 

 was difficult to estimate on account of the difference in 

 the state of maturity of the various spikes. By making 

 independent estimates on different days as long as all 

 the plants were in bloom and trying to strike an aver- 

 Ise the conclusion was reached that the plants grown in 

 the 'lighter soils had a stronger and more pronounced 

 fragrance than those grown in the heavy clay soils 

 ThI amount of fragrance given by wilting A^'ers on 

 the heavy clay soils is very perceptibly less than that 

 given off by flowers from the lighter soils. In plants 

 grown in a heavy clay loam richly manured, the fra- 

 grance was hardly perceptible and very faint even on 

 wilting. The influence of the different proportions of 

 manure and soil used was not measurable, as the ditter- 

 STce, if any, in the strength of the odor given off by 

 the different spikes was too slight to measure. 



Heavy manuring seems to have a deleterioiis effect on 

 the fragrance of Mignonette. Two plots of the same 

 number of plants growing in a solid bed were taken 

 One was manured weekly with liquid manure; the other 

 was left unraanured. The manured plants made more 

 growth and produced less but larger flowers than the 

 unmanured plants. As long as the manuring was con- 

 tinued, the unmanured plot was the most fragrant After 

 dLscon inning manuring for two weeks, the difference 

 Eecame imperceptible and ultimately the plot which had 

 teen manured became more fragrant th.an the un- 

 manured plot. The plants in the unmanured plot were 



^"t has be°en'asserted that Mignonette is most fragrant 

 when grown at a low temperature, it being a plant 

 which loves a cool atmosphere. In order to test tne 

 effect of temperature on the fragrance of Mignonette, 

 plants of the same varieties were grown m bouses 

 whose mean temperature was 50° P.. 0.5° F. and ,5 F. 

 The plants had the same soil. Those in the house

 time no difference in the fragrance between the cool 

 house plants and those grown in the medium house 

 could be detected, although there was a difterence at 

 first. Plants taken from the temperate house into the 

 cool house, on the other hand, apparently did not lose 

 their fragiince until the old ^Pi^es had been replaced 

 by new ones. From these two results it would appear 

 that the influence of temperature is not permanent 

 either as far as the flowers that came i™n'<'d'ate'Jfl"°^^^ 

 the temperature influence is concerned or those flowers 

 that are not yet developed. But the temporary mfluence 

 of temperature is of longer duration in the case of 

 flowers taken from a warm house into a cool house 

 than from a cool house into a warm house. The differ- 

 ence in odor between plants grown in a warm and a 

 cool house is probably due to the more ready volatiliza- 

 tion of the ethereal oils in a warm temperature. This 

 volatilization, when once set up, is probably less eas ly 

 checked or accelerated above a 'J"™^' ™ ;■' ^^''^ ^^ 

 that rate may be; hence the tardiness of the plants to 

 react with the cooler temperature. ^ ^ j„^,^„^^^,.
