90 MUSHROOMS, HOW TO GROW THEM. 
“3. Equal parts of horse dung, cow dung, and 
sheep’s dung, with the addition of some rotten leaves or 
old hotbed dung. 
“4. Horse dung one part, cow dung two parts, 
sheep’s dung one part. 
“5. Horse droppings from the roads one part, cow 
dung two parts, mixed with a little loam. 
“6. Horse dung, cow dung, and loam, in equal 
parts.” 
From the above it appears that horse dung and cow 
dung are the principals in spawn. bricks; the loam is 
added for the purpose of making the other materials 
hold together; it also absorbs the ammonia, which other¬ 
wise would pass off. 
J. Burton’s Method. Erom The Kitchen and Mar¬ 
ket Garden .—Make the spawn in early spring. As cow 
manure is the principal ingredient used in making the 
bricks this should be secured before the animals get any 
green food. Store it on the floor of an open, dry, airy 
shed, and turn it every few days for a week or two. 
Then add an equal part of the following: Eresh horse 
droppings, a little loam, and chopped straw, mixed to¬ 
gether. “The whole should then be worked well 
together and then trodden down, after which it may be 
allowed to remain for a few days, when it will be required 
to be turned two or three times a week. If the weather 
be fine and dry the mass will soon be in a fit condition 
for molding into bricks, which process can be performed 
by using a mold in the same way as the brick makers, 
or, . . . the manure may be spread evenly on the 
floor to a thickness of six inches, and then be firmly 
trodden and beaten down evenly with the back of the 
spade. It should then be lined out to the required size 
of the bricks, and be cut Avith a sharp spade or turfing 
iron. In a few days the bricks will be sufficiently dry 
to handle, when they should be set up edgeways to dry
