adapted for this purpose. The different sieves to be found on the market have been tried 

 with more or less, generally less satisfactory results. In some places also Trieurs have 

 been employed. Experiments have also been made in separating Dodder seeds by the 

 different specific weight in liquids, but these could not lead to any satisfactory result, 

 because the limits of the specific weight of the two seeds overlapped. 



We early recognized the importance of having a standard - sieve for large Dodder- 

 •seeds, and to construct this we took many thousands of measurings for the purpose of 

 getting average of the largest diameters oft he seed, on the basis of which the standard- 

 sieve should be constructed. 



In the course of these experiments we struck by chance on a device which is 

 •calculated to lead the matter in quite another direction. 



An employe of our Station whose name — Louis Naday — deserves to be mentioned 

 here, made the discovery, that clover and Dodder seeds, when dropped from a certain 

 height on a porcelain - plate, rebound in a different manner. Whereas the clover seeds — 

 s6 far as they are normally developed and uninjured, rebound, without exception, out of 

 the plate, the Dodder seeds, which are of quite different elasticity, remain on it. In 

 virtue of this quality, which — so far as I know — has never yet been employed for the 

 separation of seeds, we have found a new method of cleaning seeds. The process has been 

 patented and now attempts are beeing made to construct a suitable machine. Some difficulties 

 have appeared to its application in practice, which, however, will surely be overcome by 

 technical devices. I should here only point out, that an exact separation of the seeds of 

 different elasticity can only be obtained if the seeds are dropped one by one on the hard 

 surface, otherwise they collide and spoil the result. I show you here this very -simple 

 experiment and you can convince yourselves that the separation succeeds. immediately, if 

 the seeds are dropped one by one. 



I believe the principle has a great future, for all the difficulties which are still 

 connected with the construction, of a suitable machine are outweighed by the advantage 

 that the separation of the seed (other seeds, for instance broken seeds can be also separated 

 by this method) can be effected without the necessity of using continous motiVe power. 



Of this I wished to inform you as the most important of the results obtained at 

 the Budapest Testing Station."

»Les mesures prises en France pour combattre la cuscute. 



La cuscute est, en France, un flSau pour les prairies artificielles. Pour la combattre, 

 plusieurs mesures 16gales ont 6\S prises. 



La loi generale du 1 Aout 1905, sur les fraudes en matieres commerciales, trouve son 

 application a ce sujet. Consideront que la presence de la cuscute dans une semence con- 

 stitue un vice cache, qu'elle est de nature a causer ft, I'agricultenr un prejudice centre 

 lequel il importe de la premunir, le Service de la Repression des Fraudes interprfete ainsi • 

 cette loi: 



»La vente a la culture des semences cuscut^es est tolerfie, an moins jusqu'a present, 

 mais a la condition expresse de fixer aux sacs une etiquette renseignant I'acheteur, portant 

 en caractferes bien apparents, la mention: »Non Ddcuscuteei, mention qui doit figurer 

 ^galement sur les factures de livraison. 



A d^faut d'indication sur le sac et sur la facture, la marchandise est cousider6e 

 comme »decuscut6e«, et alors elle ne doit pas renfermer plus de 10 graines de cuscute par 

 kilogramme de la marchandise, s'il s'agit de trfefle des pr6s, de luzerne, d'anthyllide, de 

 minette bu de trfefle incarnat. La tol6raiice est de 20 graines pour le trfefle blanc, le 

 trfefle hybride, les lotiers et la fl6oIe« (Le commerce des semences et la loi du 1 Aout 1905, 

 par E. Schribaux, Directeur de la Station d'Essais de Semences). 



II n'est pas inutile de faire remarquer que la tolerance dont il est ici question, tolerance 

 qui pent paraitre excessive lorsqu'on ne preud pas la peine de r6fl6chir, trouve sa justification
