two fine varieties

Shaaxi Prov.The experiment shows that the surviving rate over winter of both kindsof pastures are 100% and the growth is well developed. The Sainfoin maystand strong dry condition

and it contains more rich nutrient and coarseprotein in every period compared with Milkretch

and it is also palatablefor animals

it is a good protein forage. But the yield of Milkretch ishig-her than that of Sainfoin. The experiment shows that both of the pas-ture are of great value to spread
