having a very excellent laboratory and all that science 

 could offer. Just what the conditions are now, we are 

 not prepared to say. One fact is certain, very supe- 

 rior seed has been created by the Desprez producers, 

 and they were the first to establish a laboratory on a 

 very extended scale. They claim to sell, annually, lOO 

 tons of beet seed obtained directly from selected moth- 

 ers. Their early maturing varieties attracted for a 

 time some attention. They also attempted, with more 

 or less success, to create varieties suitable for every 

 soil and climate. But the conditions of environment 

 in many countries render doubtful if the idea has much 

 practical value. The very rich variety is known as 

 Marque I; its object being to obtain the greatest pos- 

 sible yield of sugar to the acre, soils of an average 

 depth being needed for a continuous period of four 

 years. In a very careful observation, the sugar per- 

 centage was shown to be i6. There are also Marque 



1 bis and Marque II. The former demands a very 

 deep, well worked soil and yields twenty tons to the 

 acre; the latter twenty-five tons to the acre and 15 to 

 10 i^er cent, sugar. On a soil of average fertility, 

 maturity is possible in 150 days. Then follow Marques 



2 bis, 3, 3 bis, 4 and 4 bis, etc. Besides which there 

 are many varieties intended for beet distilleries. Agents

This is a general seed grower, but who, however, 

 has met with success in his sugar-beet-selecting 

 methods. The laboratory is well equipped for the 

 selection. They start from a variety they call Supra- 

 Elite; from it are obtained the Elite. They furnish to 

 the trade annually over 200,000 pounds of beet seed.
