fact that one rabbit disliked it and seldom ate her share. At the end of 

 of the experiment lyot 3 carried the most flesh and the mixture they received 

 was used successfully throughout the year, giving support to the view that 

 a mixture of foods is better than single foods. 



The experiments show that oats can be very well replaced by cheaper 

 foods and that rabbits can be reared for the 6 weeks of their greatest growth 

 in summer at a cost of ^^ per week for concentrated food. Roughly 

 speaking it was found that it took some 15 lbs. of food to produce i lb. 

 increase live weight and this figure agrees very well with the observations 

 made by the writer many years ago when it was estimated that each rabbit 

 increased i lb. for every 12 lbs. of food consumed. During the 6 weeks 

 experimental period each rabbit produced 9 to 10 lbs. of dry and liquid 

 manure.

1306 - New Dressing Machine for Spherical Grain. — iiinstrierte landwirtschaftu he 



Zeitimg, 36th Year, Xo. 64, pp. 429-430. Berlin, August 9, 1916. 



In plate dressing machines of the usual type, seeds which are not per- 

 fectly round or those having flat surfaces on them, either stay on the plate 

 or move along very slowly and leave it reluctantly. This causes seeds 

 of inferior quality to fall into the 'hopper. 



On the other hand, in the new machine described here, (made by 

 Ernst lyOSCHE at Koenigsberg, Prussia; German Patent No. 292667), 

 a step device causes the seeds to make a kind of jump which allows them 

 to roll and to leave the plate at the proper moment. Again, the fact that 

 the external ring of the plate is adjustable, allows the individual character- 

 istics of each kind of seed to be provided for and gives most efficient se- 

 paration. Another novelty consists in the adjustability of the carrier 

 platforms situated in the annular discharge channels. In this way the 

 classification of the different kinds of grain can be varied -at will. Finally 

 the rousing shaft fixed in the feed channel is a very useful improvement ; 

 it keeps the grain in constant motion and prevents the formation of heaps. 

 The friction rids the grain of husks, stalks, etc., while sand and other impur- 

 ities are led to a sieve at the bottom of the feed channel and thus do not 

 reach the dressing plates. Fig. i shows a complete view of the machine ;

 the carrier platform p controlled through the window ; and fig. 4. is a 

 vertical section of a dressing plate and feed channel, showing also the under 

 side of a dressing plate with adjusting wing-nuts t ; the position of the rous- 

 ing shaft h is indicated together with its driving-bevel e. 



As shown in fig. i, the three pillars a of the frame function also as dis- 

 charge channels and are connected by the cross-piece h. The frame carries 

 the cylindrical feed channel c which at its upper end has a driving-bevel e, 

 running on a ball-bearing d. From this bevel the dressing plates / are sus- 

 pended by stay-bolts. The shaft h forms the axis of the bevel e. It is
