THE CLUB IN MARY'S GARDEN 179 



pigs eat the pigweed, like the toads eat insects ; but 

 it would not do to let a pig in your garden to eat up 

 the pigweed ; it is better to pull it up 

 yourself. Pigweed and ragweed 

 grow very tall. Knot-grass is also 

 a weed. It does not 

 grow as big as pigweed, 

 but it can make just as 

 much bother. It is 

 called knot-grass be- 

 cause it has roots that 

 seem to tie themselves 

 in knots with the roots 

 of other things and are 

 very hard to get all 

 out. Knot-grass has a 

 little pink flower that 

 is very pretty. Purs- 

 lane is another weed. This does not sound like a 

 weed, so sometimes people call it pusley. It has a little 

 yellow flower that shuts up very early, but you must 

 dig it out of your garden. Weeds should be pulled 

 out when they are little ; then they cannot grow big."
