Part 2

=OUR METHOD OF TESTING ORIGINAL CULTURES=

Before our Brandywine Spawn is made up in quantity, the different varieties are first tested in our own beds and accurate record of production is each day carefully made.

In this way we eliminate entirely unproductive varieties and choose only those which are most vigorous, perfect in shape and color and will make the greatest yield.

=PRICE LIST=

The fact that Jacob’s Brandywine Spawn costs a little more than any other spawn made, and that the large and most successful growers are quite willing to pay more for it, means that they find it the most profitable to use.

=The BEST is always the CHEAPEST=

Jacob’s Brandywine Spawn is made in three varieties, pure white, cream white and light brown at the following prices:

* * * * *

One brick is enough for 10 square feet of bed surface.

1 brick or more (by mail, prepaid), 35 cents a brick. 5 bricks or more (by express, not prepaid), 25 cents a brick. 25 bricks or more (by exp. or frt., not prep’d), 20 cts. a brick. 50 bricks or more (by exp. or frt., not prep’d), 18 cts. a brick. 135 bricks (one case) (by exp. or frt., not prepaid), 15 cents a brick.

Stamps, money orders or checks should accompany orders to insure prompt shipment.

On the following pages will be found full and complete instructions for those who wish to grow Mushrooms for home use as well as for the market.

=SELECTION OF A PLACE TO GROW MUSHROOMS=

Any cellar which maintains a uniform temperature of from 45 to 65 degrees may be used.

Any barn or outbuilding may be supplied with heat and used successfully, but the temperature should be kept as nearly uniform as possible.

Any cold building which it is not practical to heat, may be planted during September while the weather is still warm and the beds allowed to get cold and even freeze up solid during winter months. Such beds will produce the finest kind of mushrooms during the early spring months when the temperature rises sufficiently.

The larger growers usually build houses especially for mushrooms and heat by means of hot water pipes. Some use abandoned caves or mines, while florists often grow mushrooms successfully under greenhouse benches.

=PREPARATION OF MANURE=

Select fresh horse manure where wheat or oats straw has been used as bedding.

Never use old manure or manure mixed with shavings or sawdust.

Place the fresh manure in a neat pile and cover with two or three inches of earth.

In the course of three or four days turn the manure over, shaking and mixing the earth in thoroughly. Add water if necessary to keep the manure in reasonably moist condition.

Cover again with earth which will be sufficient, and allow the pile to heat, through the action of bacteria in the manure, for five or six days. Then turn again, shaking up thoroughly each time, and turning the outer dried or whitened portion of the pile toward the centre. Add water with a sprinkler when necessary to keep plenty of moisture. After about four turnings in this way, covering a period of three or four weeks the manure will be sufficiently rotted and decomposed to make into the beds.

=MAKING THE BEDS=

The manure should be placed on the floor or prepared bed spaces to a depth of 8 to 10 inches in winter weather. In warm weather 6 or 7 inches are enough.

The compost should be compressed in making the bed and provided it is not too wet it may be tramped, which prevents too much drying out, while the manure is heating in the beds.
